Structure rtrs_srv is used for sessions so in order to avoid confusions
rename it to rtrs_srv_sess.
All changes were done with the help of following Coccinelle script:

We changed the rnbd_srv_sess_dev_force_close to use try-lock
because rnbd_srv_sess_dev_force_close and process_msg_close
can generate a deadlock.
Now rnbd_srv_sess_dev_force_close would do nothing
if it fails to get the lock. So removing the force_close
file should be moved to after the lock. Or the force_close
file is removed but the others are not removed.

The forceful close of an exported device is required
for the use case, when the client side hangs, is crashed,
or is not accessible.
There have been cases observed, where only some of
the devices are to be cleaned up, but the session shall
remain.
When the device is to be exported to a different
client host, server side cleanup is required.
