libpayload: Add interrupt-queue underrun recovery to EHCI
If the queue of an interrupt transfer runs out, we have to reset
the queue head. This also introduces the use of a spare transfer
descriptor (TD) in interrupt queues, which assures, that a processed
TD won't be reused until the host controller has written it back
from his overlay.
