Re: kern/59681: npf: missing locking around inpcb_lookup in uid/gid checks

[Taylor R Campbell <riastradh%NetBSD.org@localhost>]

Longer-term, we need to make inpcb access work under pserialize(9).
But that's a larger change that requires some care -- e.g., we really
don't want to do a pserialize_perform for every socket close, so we'll
need to queue them for batches of garbage collection of some sort.
For now, and particularly for correctness in netbsd-11, we'll just
need to take softnet_lock.
