    sys/dev/disk/dm: Fix dm-delay behavior for compatibility with Linux
    
    The original Linux dm-delay's behavior was to
    (A) use read params for write if write params aren't specified,
    but not to
    (B) have no delay for write if write params aren't specified.
    
    DragonFly currently does (B) and this wasn't intentional,
    so change it to (A) for compatibility with Linux dm-delay.
