sparc64: Fix bugs in get_user_pages_fast() wrt. THP.
The large PMD path needs to check _PAGE_VALID not _PAGE_PRESENT, to
decide if it needs to bail and return 0.
pmd_large() should therefore just check _PAGE_PMD_HUGE.
Calls to gup_huge_pmd() are guarded with a check of pmd_large(), so we
just need to add a valid bit check.
