Pi-Hsun Shih f4169c4e91 wireless: Use offsetof instead of custom macro. 
commit 6989310f5d upstream.

Use offsetof to calculate offset of a field to take advantage of
compiler built-in version when possible, and avoid UBSAN warning when
compiling with Clang:

==================================================================
