userfaultfd: hugetlbfs: allow registration of ranges containing huge pages
Expand the userfaultfd_register/unregister routines to allow VM_HUGETLB
vmas. huge page alignment checking is performed after a VM_HUGETLB vma
is encountered.
Also, since there is no UFFDIO_ZEROPAGE support for huge pages do not
return that as a valid ioctl method for huge page ranges.
