In case of MLO same adapter maps to both vdevs. Tx is done with
primary link vdev pool. In link switch case vdev0 flow pool is
deleted and traffic will continue to flow with same vdev0 flow_id
This is resulting in packets drops within the driver due non-availibilty
of flow pool.
Fix this by skipping flow pool deletion in case of STA MLO connection.
