[PATCH 06/12] mm: hugetlb_vmemmap: rename vmemmap_remap_pte() to vmemmap_optimize_pte()

[Muchun Song <songmuchun@bytedance.com>]

Both optimization and restoration update vmemmap PTEs by remapping them,
so "remap" does not identify the callback's role.  Use "optimize" for the
optimization callback to match "restore" and make the two directions
explicit and consistent.

No functional change intended.
