ubifs: Convert do_readpage() to take a folio

All the callers now have a folio, so pass it in, and convert do_readpage()
to us folios directly.  Includes unifying the exit paths from this
function and using kmap_local instead of plain kmap.  This function
should now work with large folios, but this is not tested.
