Add one new array (marked with __maybe_unused to prevent gcc warning about
"defined but not used" with W=1), then we can remove rnbd_access_mode_str
and rnbd-common.c accordingly.

Add event tracing mechanism for following routines:
- create_sess()
- destroy_sess()
- process_rdma()
- process_msg_sess_info()
- process_msg_open()
- process_msg_close()
How to use:
1. Load the rnbd_server module
2. cd /sys/kernel/debug/tracing
3. If all the events need to be enabled:
echo 1 > events/rnbd_srv/enable
4. OR only speific routine/event needs to be enabled e.g.
echo 1 > events/rnbd_srv/create_sess/enable
5. cat trace
5. Run some workload which can trigger create_sess() routine/event
