  Log:
  Be more careful handling off-channel frames: if the driver (wrongly)
  sends frames up the stack after changing the current channel then
  the lookup by ieee channel number may fail leaving a null ptr in
  se_chan; if this happens fallback to the channel recorded when the
  frame is processed (curchan).  Since the frame doesn't contribute
  to scan results for the sta this is acceptable.
