Configure the interrupt IN endpoint of usb-kbd as Isoch IN and queue one
TD. The TD is deferred by a microframe, the kick timer retries it,
usb-kbd NAKs, and a second doorbell retries it again. The TD has to stay
pending both times and the controller has to keep running.
Without the fix QEMU aborts in the timer retry. The endpoint setup is
taken from the reproducer attached to #3886.
