qcacld-3.0: Increase SAP ACS scan priority to high from low

The function sap_goto_channel_sel triggers the pre start bss
scan for SAP. After this scan is queued, the hostapd process
gets scheduled after 3 secs and proceeds to select the channel
to start the SAP. If scan completion for the ACS scan was not
received, it selects the default channels. ACS scan is sent to
firmware with low priority like other normal scan.
Increasing the priority of the scan will ensure that the scan
completion is done prior to the other existing scans pending on
the queue.

Escalate the priority of the ACS scan from low to high.
