mm: zswap: modify zswap_compress() to accept a page instead of a folio
For zswap_store() to be able to store a large folio by compressing it one
page at a time, zswap_compress() needs to accept a page as input. This
will allow us to iterate through each page in the folio in zswap_store(),
compress it and store it in the zpool.
