Peter Xu 878b0c4516 mm/gup: handle hugetlb for no_page_table() 
no_page_table() is not yet used for hugetlb code paths.  Make it prepared.

The major difference here is hugetlb will return -EFAULT as long as page
cache does not exist, even if VM_SHARED.  See hugetlb_follow_page_mask().

Pass "address" into no_page_table() too, as hugetlb will need it.
