[PATCH] net/mlx5: fix modify field MAC address offset

[Viacheslav Ovsiienko]

The MAC addresses fields are 48 bit wide and are processed
by mlx5 PMD as two words. There the bug was introduced for
the offset, causing wrong action translation if action
field offset was not zero.

Fixes: 40c8fb1fd3b3 ("net/mlx5: update modify field action")
