qcacld-3.0: Fix STA disconnect when SAP detected radar

Sap is started on freq 5640Mhz with BW 160Mhz and radar event
generated, and then SAP moves to freq 5680Mhz.
But before the move done, the regdomain update (because of Radar
detection) will trigger the wlansap_get_chan_band_restrict to run
and further move to SAP to freq 5180Mhz.
The client side still get old CSA event with 5680Mhz, and switch to
5680Mhz and get Bmiss finally because actually SAP is moved to 5180Mhz.
The band restrict logic should not handle radar disabled channel.
The radar detected channel (in NOL) should be handled by SAP radar
channel switch logic only.
Fix by skip the band strict check if disabled channel is in NOL
list, let the SAP radar logic to handle channel switch.
