When mlx5 port was configured with HW Steering flow engine
(devarg dv_flow_en set to 2), PMD did not set
RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE in device flags.
This caused certain flow API calls, such as rte_flow_query(),
to obtain a port-wide lock, which is not needed.
This patch adds missing code for setting this flag.
