Flow director API does not provide a layer 2 configuration when the filter
is for layer 3 and 4 causing the translation to generic flow API to be
wrong, as not providing a mask for layer ends by using the default one.  In
this case, the Ethernet mask layer is full whereas it must be empty.

Fixes: 4c3e9bcdd52e ("net/mlx5: support flow director")
