net/mlx5: fix modify field MAC address offset

Browse Source 
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 malfunction of MODIFY_FIELD action
with MAC address fields as source or destination and
with non zero field offset.
