 Modified Files:
 	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.
