mm: khugepaged: remove redundant check for VM_NO_KHUGEPAGED
The hugepage_vma_check() called by khugepaged_enter_vma_merge() does check
VM_NO_KHUGEPAGED. Remove the check from caller and move the check in
hugepage_vma_check() up.
More checks may be run for VM_NO_KHUGEPAGED vmas, but MADV_HUGEPAGE is
definitely not a hot path, so cleaner code does outweigh.
