Kernel panic in networking code

Hey all,

It looks like there's a potential deadlock in some networking code,
specifically with ipv4 jails. I can reproduce by running Poudriere on
14-CURRENT.

I am using HardenedBSD 14-CURRENT, but we don't have any changes to
any point in the code paths that would trigger/cause this kind of
kernel panic.

I've uploaded the crash.txt file here:

`uname -a`: FreeBSD ci-08 14.0-CURRENT-HBSD FreeBSD 14.0-CURRENT-HBSD #0  hardened/current/master-n191216-7474f245a83: Wed Dec  8 22:44:04 EST 2021     shawn@ci-08:/usr/obj/usr/src/amd64.amd64/sys/HARDENEDBSD  amd64

Thanks,
