    If we are unlucky, during detach of child devices, after a uhub has detached,
    our uhci_poll_hub callout might strike. The detaching of the uhub has left
    the device member in the pipe NULL, so make sure we do not dereference it.

    We could halt the callout before detaching child devices, but it this
    would likely interfere with proper servicing the child devices while
    they are still around.
