In USB pollchar, wait for packet before re-checking USB out len

This probably wouldn't actually cause a problem, but it seems more
reliable to wait for a packet interrupt before re-reading the packet
OUT len register. This could avoid spinning while waiting for a USB
packet, which seems like a good thing.
