Subject: net: sched: Use FIELD_SIZEOF directly instead of reimplementing its
 function
Patch-mainline: v4.20-rc1
Git-commit: cb205a817444f4838547e9f19438b96fdc32d5b6
References: bsc#1109837

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