====================
amt: fix several bugs

This patchset fixes several bugs in amt module

First patch fixes typo.

Second patch fixes wrong return value of amt_update_handler().
A relay finds a tunnel if it receives an update message from the gateway.
If it can't find a tunnel, amt_update_handler() should return an error,
not success. But it always returns success.

Third patch fixes a possible memory leak in amt_rcv().
A skb would not be freed if an amt interface doesn't have a socket.
