Fix mbuf leaks on error paths

Dedup common codes in error paths (NFCI)

Don't relook up an SP/SA in opencrpyto callbacks
We don't need to do so because we have a reference to it. And also
relooking-up one there may return an sp/sav that has different
parameters from an original one.

Fix kernel panic (assertion failure) on receiving an IPv6 packet with large options
If an IPv6 packet has large options, a necessary space for evacuation can
exceed the expected size (ah_pool_item_size). Give up using the pool_cache
if it happens.

Style.

Commonalize error paths (NFC)

Fix buffer overflow on sending an IPv6 packet with large options
If an IPv6 packet has large options, a necessary space for evacuation can
exceed the expected size (ah_pool_item_size). Give up using the pool_cache
