qcacld-3.0: Ignore PCL scoring for non-DBS STA

HW is non-DBS. SAP is UP in 6 GHz. Now, when a STA connection is
attempted, the pcl for the second connection would have SAP SCC
channel with highest priority, all the 5 GHz channels with 2nd
highest priority and the 6 GHz channels with least priority.
Therefore, even if there is a strong 6 GHz candidate for STA, the
5 GHz candidate would be chosen and the SAP moves to SCC in 5 GHz.

To fix this, ignore the pcl scoring for the non-DBS concurrency
cases as the SAP can move to the channel of the best STA interface.

If the SAP is in legacy band, and if still a 6 GHz STA is chosen,
then the legacy SAP would be torn down. So, give STA the best
possible in non-DBS case.
