hugetlb: make unmap_ref_private multi-size-aware
Oops. Part of the hugetlb private reservation code was not fully converted to use hstates. When a huge page must be unmapped from VMAs due to a failed COW, HPAGE_SIZE is used in the call to unmap_hugepage_range() regardless of the page size being used. This works if the VMA is using the default huge page size. Otherwise we might unmap too much, too little, or trigger a BUG_ON. Rare but serious -- fix it.
