    s390/qeth: merge qeth_reply struct into qeth_cmd_buffer · 308946b0

    Except for card->read_cmd, every cmd we issue now passes through
    qeth_send_control_data() and allocates a qeth_reply struct. The way we
    use this struct requires additional refcounting, and pointer tracking.
    
    Clean up things by moving most of qeth_reply's content into the main
    cmd struct. This keeps things in one place, saves us the additional
    refcounting and simplifies the overall code flow.
    A nice little benefit is that we can now match incoming replies against
    the pending requests themselves, without caching the requests' seqnos.
    
    The qeth_reply struct stays around for a little bit longer in a shrunk
    form, to avoid touching every single callback.
