- setup hwgroup->handler/timer in ->prehandler() (after checking
  drive status) and in do_rw_taskfile() only send a command
- make pre_task_mulout_intr() transfer first data block itself
  instead of calling ->handler() so we don't have to play tricks
  with hwgroup->handler/timer in task_mulout_intr()
