mm: remove unused hugepage for vma_alloc_folio()

Browse Source 
The hugepage parameter was deprecated since commit ddc1a5cbc0
("mempolicy: alloc_pages_mpol() for NUMA policy without vma"), for
PMD-sized THP, it still tries only preferred node if possible in
vma_alloc_folio() by checking the order of the folio allocation.
