From: Md Haris Iqbal <haris.iqbal@xxxxxxxxxxxxxxx>
Since the removal of the session sysfs can also be called from the
function destroy_sess, there is a need to protect the call from the
function rnbd_srv_sess_dev_force_close
Fixes: 786998050cbc ("block/rnbd-srv: close a mapped device from server side.")
