[IrDA]: Fix RCU lock pairing on error path
irlan_client_discovery_indication calls rcu_read_lock and rcu_read_unlock, but returns without unlocking in an error case. Fix that by replacing the return with a goto so that the rcu_read_unlock always gets executed. Signed-off-by: Josh Triplett <josh@freedesktop.org> Acked-by: Paul E.
