mm/mremap: use pmd/pud_poplulate to update page table entries

pmd/pud_populate is the right interface to be used to set the respective
page table entries.  Some architectures like ppc64 do assume that
set_pmd/pud_at can only be used to set a hugepage PTE.  Since we are not
setting up a hugepage PTE here, use the pmd/pud_populate interface.
