Joe Perches 8c7fbe5795 stddef.h: move offsetofend inside #ifndef/#endif guard, neaten
Commit 3876488444 ("include/stddef.h: Move offsetofend() from vfio.h
to a generic kernel header") added offsetofend outside the normal
include #ifndef/#endif guard.  Move it inside.

Miscellanea:

o remove unnecessary blank line
o standardize offsetof macros whitespace style
