mpage: use folios in bio end_io handler 

JIRA: https://issues.redhat.com/browse/RHEL-27741

    mpage: use folios in bio end_io handler

    Use folios in the bio end_io handler.  This conversion does the
    appropriate handling on the folios in the respective end_io callback and
    removes the call to page_endio(), which is soon to be removed.
