x86/mm: Fix {pmd,pud}_{set,clear}_flags()
commit 842cef9113c2120f74f645111ded1e020193d84c upstream.
Just like pte_{set,clear}_flags() their PMD and PUD counterparts should
not do any address translation. This was outright wrong under Xen
(causing a dead boot with no useful output on "suitable" systems), and
produced needlessly more complicated code (even if just slightly) when
paravirt was enabled.
