[Bug 290768] if_wg(4): handshake response has src and dst reverse

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=290768

I don't really see how that's possible at the moment; we get that addrerss one
of a few different ways:

1.) wg(8) set it via the ioctl interface, but it only does that for AF_INET /
AF_INET6
2.) When we receive a valid handshake initiation
3.) When we receive a valid handshake response
4.) When we receive a valid packet over the tunnel

For #2 - 4, those are pulled from the `pkt->p_endpoint`, which is populated in
wg_input().  If we didn't get an AF_INET / AF_INET6 address *there*, the packet
is dropped.  You say that IPv6 is disabled, but I don't think opnsense produces
any kernel configs with it completely ripped out, so EAFNOSUPPORT from it being
an AF_INET6 is likely not what's happened -- something presumably went wrong in
the sosend() path instead.
