This is a fix to an issue where the driver sends its periodic WELLNESS
command to the controller after the driver shut it down.This causes the
controller to crash. The window where this can happen is small, but it
can be hit at around 4 hours of constant resets.

When sending a reset fib we shouldn't rely on the scsi command,
but rather set the TMF status in the map_info->reset_state variable.
That allows us to send a TMF independent on a scsi command.

During EEH recovery number of online CPU's might change thereby changing
the number of MSIx vectors. Since each fib is allocated to a vector,
changes in the number of vectors causes fib to be sent thru invalid
vectors.In addition the correct number of MSIx vectors is not updated in
the INIT struct sent to the controller, when it is reinitialized.
Fixed by reassigning vectors to fibs based on the updated number of MSIx
vectors and updating the INIT structure before sending to controller.

The method to allocate and free FIB's in the present code utilizes
spinlocks. Multiple IO's have to wait on the spinlock to acquire or free
fibs creating a performance bottleneck.
An alternative solution would be to use block layer tags to keep track
of the fibs allocated and freed. To this end aac_fib_alloc_tag was
created to utilize the blk layer tags to plug into the Fib pool.These
functions are used exclusively in the IO path. 8 fibs are reserved for
the use of AIF management software and utilize the previous spinlock
based implementations.
