wireguard-freebsd handshaking issue upon underlying WAN

[Ryan Roosa]

Just wanted to provide some feedback that pfSense development
snapshots of 2.6.0 running WireGuard package v0.1.5_2 include the fix
and there I have validated that removing WAN connectivity at various
intervals up to 10 minutes no longer impacts subsequent handshaking
once the connection is restored. I have not yet tested on OPNSense but
I imagine the results will match once I do (if not I will reach out).
Thanks to everyone for their efforts on resolving this one, I really
appreciate it.
