block/rnbd-srv: drop the sess_dev kobject unlocked
rnbd_srv_create_dev_session_sysfs() drops the kobject reference when it
fails. The release function is rnbd_destroy_sess_dev(), which takes
srv_dev->lock, and the caller holds that lock: the worker deadlocks on
itself. A client opening one device as "ram0" and "./ram0" gets there
through -EEXIST from kobject_add().
Have process_msg_open() drop the reference after releasing the lock, and
leave the rest of the cleanup to the release function.
Fixes: 8cee532f469b ("block/rnbd: server: sysfs interface functions")
Fixes: d3a95ccaaf4d ("block/rnbd: call kobject_put in the failure path")
