The DR TX state machine supports the following order:
modify header, push vlan and encapsulation.
Instead fs_dr would pass:
push vlan, modify header and encapsulation.

The above caused the rule creation to fail on invalid action
sequence provided error.

Fixes: 6a48faeeca10 ("net/mlx5: Add direct rule fs_cmd implementation")
