commit f53300fdaa84dc02f96ab9446b5bac4d20016c43 upstream.
Some compilers (tested with 4.8.5 from CentOS 7) fail properly process FIELD_GET inside an inline function, which ends up in a BUILD_BUG_ON. Convert inline function to a macro.
Fixes commit bf92e7685100 ("mt76: mt7615: add support for per-chain signal strength reporting") Reported in https://lkml.org/lkml/2019/9/21/146
