qcacld-2.0: Clear up DFS rules for multiple interfaces
Currently if STA connects to a DFS channel AP, SAP fails to start
in non-DFS channel.
To fix this issue, clear up DFS rules in sap_check_mcc_valid.
For STA+SAP mode, if STA exists, SAP can't start in DFS channel.
For SAP+SAP mode, DFS channel can't be selected if they work in
MCC mode.
