qcacld-3.0: Enhance SAP concurrency check to cover AP channel switch case
SAP(Go) concurrency check is mainly used for two purposes:
1) When new GO/SAP session is coming up and needs to check if
this session's channel can co-exist with existing GO/SAP
sessions. For example, in case of single radio platform, MCC for
SAP/GO+SAP/GO is not supported, in such case this API should
prevent bringing the second connection.
2)There is already existing SAP+GO combination but due to upper
layer notifying LTE-COEX event or sending command to move one of
the connections to different channel. In such cases before moving
existing connection to new channel, check if new channel can
co-exist with the other existing connection. For example, one
SAP1 is on channel-6 and second SAP2 is on channel-36 and lets
say they are doing DBS, and lets say upper layer sends LTE-COEX
to move SAP1 from channel-6 to channel-149. In this case, SAP1
and SAP2 will end up doing MCC which may not be desirable result.
Add vdev_id check while checking for 2nd case. If connection with
given vdev_id exist then it is confirmed that it's a case of
channel switch rather than a new connection case.
