    floppy: use a statically allocated error counter
    
    commit f71f01394f742fc4558b3f9f4c7ef4c4cf3b07c8 upstream.
    
    Interrupt handler bad_flp_intr() may cause a UAF on the recently freed
    request just to increment the error count.  There's no point keeping
    that one in the request anyway, and since the interrupt handler uses a
    static pointer to the error which cannot be kept in sync with the
    pending request, better make it use a static error counter that's reset
    for each new request.  This reset now happens when entering
    redo_fd_request() for a new request via set_next_request().
    
    One initial concern about a single error counter was that errors on one
    floppy drive could be reported on another one, but this problem is not
    real given that the driver uses a single drive at a time, as that
    PC-compatible controllers also have this limitation by using shared
    signals.  As such the error count is always for the "current" drive.
