Currently there's limitation for Drop action that can only co-exist with
Count action.

Sample and Age actions are also able to exist with Drop within the same
flow, and this patch includes them in the Drop action validation.

Fixes: acb67cc8 ("net/mlx5: fix action flag data type")
Cc: stable@dpdk.org
