[PATCH net v2 2/2] amt: do not skip remaining handling of advertisement message

[Taehee Yoo <ap420073@gmail.com>]

When a gateway receives an advertisement message, it extracts relay
information and then it should be deleted.
But the advertisement handler doesn't do that.
So, after amt_advertisement_handler(), that message should not be skipped
remaining handling.
