Subject[PATCH] shmem: Update folio if shmem_replace_page() updates the page
Date
If we allocate a new page, we need to make sure that our folio matches
that new page. This will be solved by changing shmem_replace_page()
to shmem_replace_folio(), but this is the minimal fix.

Fixes: da08e9b79323 ("mm/shmem: convert shmem_swapin_page() to shmem_swapin_folio()")
