        src/sys/net: if_wg.c

Log Message:
wg(4): Put force_rekey state in the session, not the peer.

That way, there is a time when one thread has exclusive access to the
state, in wg_destroy_session under the peer lock, when we can clear
the state without racing against the data tx path.

This will work more reliably than the atomic_swap_uint I used before.
