When creating internal transfer flow on root table with lowerest
priority, the flow was created with max UINT32_MAX priority. It is wrong
since the flow is created in kernel and max priority supported is 16.
This patch fixes this by adding internal flow check.
Fixes: 5f8ae44dd454 ("net/mlx5: enlarge maximal flow priority")
