net/mlx5: E-Switch, Skip restore modify header between prios of same chain

Restore modify header writes the chain mapping on the packet.
This modify header and action is added on all prios connections,
and gets overwritten with the same value consecutively in prios
of the same chain.

Use the chain's modify header only for the last prio of a given tc
chain.
