block: drbd: remove a stray unlock in __drbd_send_protocol()
[ Upstream commit 8e9c523016cf9983b295e4bc659183d1fa6ef8e0 ]
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")
