qcacld-3.0: Issue connect immediately if system is in required hw mode

Issue the connect command immediately when the system is already
in the required hw mode. Currently the connect command is issued
immediately only when the concurrent connection update succeeds,
i.e., only when a set hw mode succeeds. But, when the driver is
already in the required hw mode, the return value would not be
success and the connect command is not getting issued immediately.
Fixed this by checking the return value which indicates that the
driver is already in the required hw mode, and issuing the
connect command immediately.
