frame-xchg: Allow calling frame_xchg_stop from the callback
Don't crash if the user calls frame_xchg_stop(wdev) from inside the
frame exchange's final callback. That call is going to be redundant but
it's convenient to do this inside a cleanup function for a given wdev
without having to check whether any frame exchange was actually running.
