After commit, c5f5c4db, cleancache crashes on the first successful get. This was caused by a remaining virt_to_page() call in zcache_pampd_get_data_and_free() that only gets run in the cleancache path. The patch converts the virt_to_page() to struct page casting like was done for other instances in c5f5c4db.
