libpayload: Fix interrupt-queue cleanup for OHCI
We have to free TDs more carefully if they have been processed by the
controller yet. The current code tries to force the controller to post
them back to the done queue, but that seems wrong. We can't be sure,
when they get written back. This resulted in leaking TDs with an invalid
reference to a freed interrupt queue.
The new approach: Mark the interrupt queue to be destroyed and handle
the freeing later, when the controller posted the last TD to the done
queue.
