Ignore thermal dual-chain requests from iwx(4) firmware.

Linux only acts on these requests in 11ax mode on 160MHz channels so
we can simply ignore this request for now. Prevents a warning from
being printed when we receive such a request:
  iwx0: unhandled firmware response 0x5f6/0x20000008 rx ring 64[3]
