intel: legacy: Partial revert of field get conversion

Browse Source 
commit ba54b1a276a6b69d80649942fe5334d19851443e upstream.

Refactoring of the field get conversion introduced a regression in the
legacy Wake On Lan from a magic packet with i219 devices. Rx address
copied not correctly from MAC to PHY with FIELD_GET macro.
