   chx_handle_intr -> chx_handle_intr -> preempt

We can't use R0 passing as an argument to preempt.

Thanks to Jeremy Drake to catch this questionable change.

While the value LEN is used for drivers for other machines to prepare
receiving buffer in hardware USB core, it is not used in STM32F103
which has dedicated hardware memory in the USB core.
