[INET]: Consolidate xxx_frag_alloc()
Just perform the kzalloc() allocation and setup common fields in the inet_frag_queue(). Then return the result to the caller to initialize the rest. The inet_frag_alloc() may return NULL, so check the return value before doing the container_of(). This looks ugly, but the xxx_frag_alloc() will be removed soon. The xxx_expire() timer callbacks are patches, because the argument is now the inet_frag_queue, not the protocol specific queue.
