#1696573 — [PATCH 3.18 12/60] stddef.h: move offsetofend inside #ifndef/#endif guard, neaten

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

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
