qcacld-3.0: cache SAP current oper bw in vdev mlme priv obj

SAP operating bandwidth may get updated due to concurrencies.
This might be temporary and SAP moves back to its original
bandwidth once concurrency is gone. So, add set and get APIs
to maintain the SAP current operating bandwidth.
These can be used during/after bandwidth update operations.
