frame-xchg: Don't call frame_xchg_destroy directly

Browse Source 
frame_xchg_destroy is passed as the wiphy radio work's destroy callback
to wiphy.c.  If it's also called directly in frame_xchg_exit, there's
going to be a use-after-free when it's called again from wiphy_exit, so
instead use wiphy_radio_work_done which will call frame_xchg_destroy and
forget the frame_xchg record.
