qcacld-3.0: Prevent 2.4G connection when SAP is on DFS channel

On single MAC devices, when a SAP or P2P-GO is already operating
on a DFS channel, MCC mode is not allowed. It is  currently
possible, even with a SAP on DFS channel, to connect to a 2.4G
AP using the command: iw interface connect SSID [AP freq]
Add additional checks in policy manager to prevent this
MCC situation.
