mm/hugetlb: remove unnecessary huge_ptep_set_access_flags() in hugetlb_mcopy_atomic_pte()
There is no need to update the hugetlb access flags after just setting the hugetlb page table entry by set_huge_pte_at(), since the page table entry value has no changes. Thus remove the unnecessary huge_ptep_set_access_flags() in hugetlb_mcopy_atomic_pte().
