qcacld-2.0: Fix SAP ACS channel selection failure
Start SAP on channel 161 in 5G by ACS. Then kill
and restart hostapd in 2.4g by ACS, result is failed.
The reason is the sap_config->channel including a
stale channel 161, the ACS will be skipped and driver
picks up the 161 as ACS result. Hostapd checks that
the 161 is not in the 2.4G and fail the start request.
The fix is to add back "reset sap_config->channel to 0"
code to wlan_hdd_cfg80211_start_acs function,
which was removed by an old commit -
