Linux: only allow one-page folios for writepages
Add a check to ensure that large folio support hasn't been
inadvertently set on for the address space that is passed to writepages.
This should only happen if OpenAFS explicitly enables large folio
support.
The current OpenAFS support for folios is folio-aware, but does not take
advantage of large folios.
In order to support large folios (a folio with multiple contiguous
pages) a filesystem must opt-in by explicitly setting the min_order on a
inode's address space during inode's creation/initialization (e.g.
calling mapping_set_large_folios, mapping_set_folio_order_range, etc.).
Add an osi_Assert at the beginning of afs_linux_writefolio_cb that
checks to see if the folio is a large folio.
