amt: fix return value of amt_update_handler()

[ Upstream commit ac1dbf55981b88d64312858ea06e3e63001f085d ]

If a relay receives an update message, it lookup a tunnel.
and if there is no tunnel for that message, it should be treated
as an error, not a success.
But amt_update_handler() returns false, which means success.
