[PATCH v2 4/4] include: Remove FIELD_SIZEOF() and sizeof_field() macros

[Kees Cook <keescook@chromium.org>]

From: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com>

The common function used to find struct member size is sizeof_member().
Remove the now unused FIELD_SIZEOF() and sizeof_field() macros.
