FROMGIT: BACKPORT: mm: swap: entirely map large folios found in swapcache

When a large folio is found in the swapcache, the current implementation
requires calling do_swap_page() nr_pages times, resulting in nr_pages page
faults.  This patch opts to map the entire large folio at once to minimize
page faults.  Additionally, redundant checks and early exits for ARM64 MTE
restoring are removed.
