-bus->intr_context issues:
- - intr_context is raised when the USB lock is dropped to call the call back
- for usb_transfer_complete(), then some other cpu can run, take the lock
- and end up triggering an "intr_context != 0" condition.
- - usb_transfer_complete() is sometimes called with host intr lock held,
- sometimes with usb lock
- - hardware interrupt takes host intr lock to protect intr_context, but
- software interrupt takes USB lock.
- - need to re-consider soft_intr() API
