qcacld-3.0: Don't stop netdev queues on link switch failure

Browse Source 
If link switch connection fails due to any reason the netdev
queues are stopped which leads to NUD failure and finally results
in connection teardown.

As we have one non-transitioning link for data transmission
in case of link switch, don't disable the netdev queues.
