usb_cdcacm.c: Fixups for usb_cdcacm_tx().
- Check if we're transmitting (instead of how many bytes are left
untransmitted) before bailing, in case we're transmitting a
zero-length packet.
- Set transmitting=1 before setting the endpoint valid to avoid races
with the USB interrupt.
- Eliminate some duplicated code.
