Log Message:
Fix memory leak of llentry#la_opaque

llentry#la_opaque which is for token ring is allocated in arp.c
and freed in arp.c when freeing llentry. However, llentry can be
freed from other places, e.g., lltable_free. In such cases,
la_opaque is never freed.

To fix that, add a new callback (lle_ll_free) to llentry and
register a destruction function of la_opque to it. On freeing a
llentry, we can surely free la_opque via the callback.
