[PATCH v4 01/18] net/mlx5: fix invalid flow attributes

[Suanming Mou]

In the function flow_get_drv_type(), attr will be read in non-HWS mode.
In case user call the HWS API in SWS mode, attr should be placed in
HWS functions, or it will cause crash.

Fixes: 572801ab860f ("ethdev: backport upstream rte_flow_async codes")
