[PATCH v1] net/mlx5: fix aggr affinity pattern create failures

[Rongwei Liu]

The mlx5 PMD attempts to validate the pattern template
by creating an internal table under group non-zero.

Aggr_affinity is only supported under root table and skip
its validation. Table create still fails due to definer
translation error.
