We missed using the variable length string macros in several
tracepoints. Fixed them in this change.
There's probably more useful macros that we can use to print
others like flags etc. But I'll submit sepawrate patches for
those at a future date.

Introduced a new field conn_id in TCP_Server_Info structure.
This is a non-persistent unique identifier maintained by the client
for a connection to a file server. For this, a global counter named
tcpSesNextId is maintained. On allocating a new TCP_Server_Info,
this counter is incremented and assigned.
Changed the dynamic tracepoints related to reconnects and
crediting to be more informative (with conn_id printed).
Debugging a crediting issue helped me understand the
important things to print here.
Always call dynamic tracepoints outside the scope of spinlocks.
To do this, copy out the credits and in_flight fields of the
server struct before dropping the lock.

There is at least one suspected bug in crediting changes in cifs.ko
which has come up a few times in the discussions and in a customer
case.
This change adds tracepoints to the code which modifies the server
credit values in any way. The goal is to be able to track the changes
to the credit values of the session to be able to catch when there is
a crediting bug.

SMB3 crediting is used for flow control, and it can be useful to
trace for problem determination how many credits were acquired
and for which operation.
Here is an example ("trace-cmd record -e *add_credits"):
cifsd-9522 [010] .... 5995.202712: smb3_add_credits:
server=localhost current_mid=0x12 credits=373 credits_to_add=10
cifsd-9522 [010] .... 5995.204040: smb3_add_credits:
server=localhost current_mid=0x15 credits=400 credits_to_add=30

We only had dynamic tracepoints on errors in flush
and close, but may be helpful to trace enter
and non-error exits for those. Sample trace examples
(excerpts) from "cp" and "dd" show two of the new
tracepoints.

If responses take longer than one second from the server,
we can optionally log them to dmesg in current cifs.ko code
(CONFIG_CIFS_STATS2 must be configured and a
/proc/fs/cifs/cifsFYI flag must be set), but can be more useful
to log these via ftrace (tracepoint is smb3_slow_rsp) which
is easier and more granular (still requires CONFIG_CIFS_STATS2
to be configured in the build though).

In debugging reconnection problems, want to be able to more easily
trace cases in which the server has marked the SMB3 session
expired or deleted (to distinguish from timeout cases).

Although dmesg logs and wireshark network traces can be
helpful, being able to dynamically enable/disable tracepoints
(in this case via the kernel ftrace mechanism) can also be
helpful in more quickly debugging problems, and more
selectively tracing the events related to the bug report.
This patch adds 12 ftrace tracepoints to cifs.ko for SMB3 events
in some obvious locations. Subsequent patches will add more
as needed.
Example use:
trace-cmd record -e cifs
<run test case>
trace-cmd show
Various trace events can be filtered. See:
trace-cmd list | grep cifs
for the current list of cifs tracepoints.
Sample output (from mount and writing to a file):
root@smf:/sys/kernel/debug/tracing/events/cifs# trace-cmd show
