[PATCH v10 26/37] mm: vma_alloc_anon_folio_pmd: pass raw fault address to vma_alloc_folio

Drop the redundant HPAGE_PMD_MASK alignment at the callsite.
NUMA interleave is not affected by the raw address; the ilx
calculation shifts addr >> PAGE_SHIFT >> order, dropping
sub-page bits regardless of alignment. post_alloc_hook will
use the raw address for cache-friendly zeroing.
