Tested on RTL8851BE (rtw89_8851be), applied on top of wireless-next at
base-commit ca800a9302764c445de0da0e84d2252400a770ee.

This chip declares BIT(NL80211_BAND_2GHZ) in support_bands and does not
set RTW89_QUIRK_DISABLE_2GHZ, so it takes the first branch of the new
logic -- the path that has to keep behaving exactly as before. No
regression observed:

 - driver probes cleanly, firmware 0.29.41.3 loads, no WARNs and no
   backtraces in dmesg
 - both bands still enumerate in 'iw phy': 14 channels on 2.4 GHz,
   24 channels on 5 GHz
 - association and traffic verified on both bands separately, 2.4 GHz
   (channel 6) and 5 GHz (channel 36)
