    emdtv(4): Fix issues in detach.

    - Use config_detach_children, and do it up front, and handle failure
      (not relevant for yanking usb but relevant for drvctl which doesn't
      pass DETACH_FORCE).

    - Fix teardown order: stop interrupts so we stop issuing new work,
      and _then_ wait for pending work to drain and destroy the
      workqueue.

    - Omit needless empty  mutex_enter(lock); mutex_exit(lock)  dance
      which probably only appeared necessary because of the wrong
      teardown order.
