net/mlx5: fix shared age action validation

[ upstream commit 4165bfd ]

Previous patch added support of shared age action.
This feature is supported on group 1 and higher, and validation was
added accordingly.
On FDB table the group 0 is skipped to improve performance.
As a result the mentioned validation is not relevant for transfer rules.
This patch adds the required check to ensure proper validation.

Fixes: f9bc527 ("net/mlx5: allow age modes combination")
