arm64: hugetlb: fix the wrong address for several functions
The libhugetlbfs meets several failures since the following functions do not use the correct address: huge_ptep_get_and_clear() huge_ptep_set_access_flags() huge_ptep_set_wrprotect() huge_ptep_clear_flush() This patch fixes the wrong address for them.
