[PATCH 2/4] RDMA/srpt: Make debug output more detailed

[Bart Van Assche <bvanassche@acm.org>]

Since the session name by itself is not sufficient to uniquely identify a
queue pair, include the queue pair number. Show the ASCII channel state
name instead of the numeric value. This change makes the ib_srpt debug
output more consistent.
