wifi: wireless: return primary channel regardless of DUP
Currently in case DUP bit is not set we don't return the primary channel for 6 GHz Band, but the spec says that the DUP bit has no effect on this field: 9.4.2.249 HE Operation element: The Duplicate Beacon subfield is set to 1 if the AP transmits Beacon frames in non-HT duplicate PPDU with a TXVECTOR parameter CH_BANDWIDTH value that is up to the BSS bandwidth and is set to 0 otherwise. So remove the condition for returning primary channel based on DUP. Since the caller code already marks the signal as invalid in case the indicated frequency is not the tuned frequency, there's no need to additionally handle this case here since that's already true for duplicated beacons on the non-primary channel(s).
