qcacmn: Don't Scan same mac frequencies, if low latency SAP present

Telusuri Sumber 
Currently, Scan list is trimmed based on low latency sap frequency.
But even after removal of 6 GHz frequencies from scan list,
host receives scan events for 6 GHz frequencies because rnr info
is updated and hint bssids and hint ssids are added due to which
FW scans 6 GHz frequencies also.

Fix is to update hint_bssid and hint_s_ssid to those frequencies
only which are allowed to be scanned in case low latency sap is up.
