[PATCH] Fix oops in alloc_zeroed_user_highpage() when page is NULL

The generic and IA-64 versions of alloc_zeroed_user_highpage() don't
check the return value from alloc_page_vma().  This can lead to an oops
if we're OOM.

This fixes my oops on PPC64, but I haven't got an IA-64 machine/compiler
handy.
