qcacld-3.0: Remove logic to disconnect STA on VDEV delete

With Vdev delete not using serialization, no need to disconnect
any STA with connection in progress.

The logic was added to remove the active connect command from
serialization queue so that vdev delete can complete before hdd
time out.

Now as vdev delete is not using the serialization remove this.
