pcd_enumerate: Avoid disabling interrupt during endpoint refill
The old implementation has a big local_irq_save() / restore() around the
endpoint re-fill routine. This disables interrupts for a long time,
psossibly causing lost interrupts.
The new implementation works around this by disabling the USB (UDP)
interrupt only, rather than disabling all interrupts on the system.
