qcacld-3.0: Update roam scan freq list for partner link

Currently, host driver updates only assoc link channel to
firmware through roam_scan_chan list. Firmware may issue
an additional scan if it finds partner link channels in
the RNR info but not present in the roam scan channel list.

To avoid additional scan, send all link channels to the firmware.
