ceph: use a folio in the inline read branch of ceph_filemap_fault()

Convert find_or_create_page() to __filemap_get_folio(), keeping the
existing GFP constraint. Saves three calls to compound_head().

The __ceph_do_getattr() locked page plumbing is converted separately,
so pass &folio->page for now.
