Fixes the same bug as b43790eedd31e9535b89bbfa45793919e9504c34 and
9aed8614af5a05cdaa32a0b78b0f1a424754a958 where the return value of
pte_*mksoft_dirty was being ignored.
To be sure that no other pte/pmd "mk" function return values were
being ignored, I annotated the functions in
arch/x86/include/asm/pgtable.h with __must_check and rebuilt.
