[INET]: Consolidate the xxx_frag_destroy
To make in possible we need to know the exact frag queue
size for inet_frags->mem management and two callbacks:
* to destoy the skb (optional, used in conntracks only)
* to free the queue itself (mandatory, but later I plan to
move the allocation and the destruction of frag_queues
into the common place, so this callback will most likely
be optional too).
