block: drbd: remove a stray unlock in __drbd_send_protocol()
There are two callers of this function and they both unlock the mutex so this ends up being a double unlock. Fixes: 44ed167da748 ("drbd: rcu_read_lock() and rcu_dereference() for tconn->net_conf") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
