mm/hugetlb: add missing VM_FAULT_SET_HINDEX in hugetlb_wp
commit 1cb9dc4b475c ("mm: hwpoison: support recovery from HugePage
copy-on-write faults") added support to use the mc variants when coping
hugetlb pages on CoW faults.
Add the missing VM_FAULT_SET_HINDEX, so the right si_addr_lsb will be
passed to userspace to report the extension of the faulty area.
