glusterd: Disconnected bricks of 'stale' volume before deleting it.
If glusterd_delete_bricks is called before glusterd got the DISCONNECT event
from the brick that was stopped, then glusterd_brick_rpc_notify would
dereference a free'd brickinfo. This can happen if the brick had not been
disconnected before.
