Scenario: 1. Start SAP on any potential LTE-COEX channel. 2. SAP would restart when it gets the event of unsafe channel. Observation: SAP restarts on a channel not in ACS channel list. Expectation: SAP should restart in channels given by the user space only which are configured by hostapd. Issue with driver: Currently in wlansap_filter_ch_based_acs, the driver eliminates the channels based upon the ACS start, and end channel, and not the channel list, which can lead to almost all the channels being picked, and none eliminated if the start channel was 1, and end channel was 165, even when only two channels, say 1 and 165 only were present in ACS channel list. Fix: Fix is to eliminate all the candidate channels which were not part of the ACS channel list, and pick only those channels that were part of initial do_acs request.
