RDMA/core: Add an option to display driver-specific QPs in the rdmatool
Utilize the -dd flag (driver-specific details) in the rdmatool
to view driver-specific QPs which are not exposed yet.
Add the netlink attribute to mark request to convey driver details and
use it to return QP subtype as a string.
