From: Mordechay Goodstein <mordechay.goodstein@xxxxxxxxx>
Currently in case DUP bit is not set we don't return the primary
channel for 6Ghz Band (UHB), but from spec seems that
DUP has no affect on primary channel for UHB,
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.
About RSSI for DUP beacon no need to mark it as invalid, due to the
code calling the function check marks signal invalid in case beacon
freq is not the freq we received it on, which is the case for DUP beacon
on non primary channels.
