From: Joe Perches <joe@perches.com>

commit 8c7fbe5795a016259445a61e072eb0118aaf6a61 upstream.

Commit 3876488444e7 ("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
