qcacld-3.0: Avoid dp_ops access during FTM mode on failure

During FTM mode start modules there is possibility  from recovery path
bus bw timer stop is being called before dp_ops gets initialized.
This will lead to accessing uninitialized dp_ops access, to avoid this
check for conn mode before accessing the dp_ops and skip timer stop.
