net/mlx5: DR, update query of HCA caps for EC VFs

Browse Source 
This change is needed to use EC VFs with metadata based steering.

There was an assumption that vport was equal to function ID. That's
not the case for EC VF functions. Adjust to function ID and set the
ec_vf_function bit accordingly.

Fixes: 9ac0b12824 ("net/mlx5: Update vport caps query/set for EC VFs")
