x86/mm: Fix vmalloc_fault to use pXd_large
commit 18a955219bf7d9008ce480d4451b6b8bf4483a22 upstream.
Gratian Crisan reported that vmalloc_fault() crashes when CONFIG_HUGETLBFS
is not set since the function inadvertently uses pXn_huge(), which always
return 0 in this case. ioremap() does not depend on CONFIG_HUGETLBFS.
Fix vmalloc_fault() to call pXd_large() instead.
