netfilter: conntrack: destroy functions need to free queued packets
queued skbs might be using conntrack extensions that are being removed,
such as timeout. This happens for skbs that have a skb->nfct in
unconfirmed state (i.e., not in hash table yet).
This is destructive, but there are only two use cases:
- module removal (rare)
- netns cleanup (most likely no conntracks exist, and if they do,
they are removed anyway later on).
