qcacld-3.0: Adding policy manager check in roam done
In ROAM DONE event handling, policy mgr restart sap is not invoked after
updating the connection info and hw mode info thus not restarting the sap
after roam sync
To solve this, adding policy manager check after updating the policy
manager connection table.
