LOR in pf on 6.2

[Bill Marquette]

Been having some kernel locks on some machines at work, not sure if
this LOR is related (and I see an XXX LOR comment in the code too, so
I'm guessing it's been seen before) although I have certainly had some
of the machines lock during bootup right around the place that this
LOR prints out.

Jan 29 12:11:46 1st 0xc09e4420 pf task mtx (pf task mtx) @
/usr/src/sys/contrib/pf/net/pf.c:6386
Jan 29 12:11:46 2nd 0xc0a5142c udp (udp) @ /usr/src/sys/contrib/pf/net/pf.c:2744

I've got a couple machines that reliably lock w/in 24 hours or so of
uptime, I can easily test any source patches on them.  All machines
are built off of FreeBSD 6.2-RELEASE-p10 sources.  Thanks
