Subject: net: qede: Use FIELD_SIZEOF directly instead of reimplementing its
 function
Patch-mainline: v4.20-rc1
Git-commit: e208cd5e41b400d90d5ba71981c7877e437671cc
References: bsc#1104393 FATE#325891 bsc#1104389 FATE#325890

FIELD_SIZEOF is defined as a macro to calculate the specified value. Therefore,
We prefer to use the macro rather than calculating its value.
