Bill Richardson 41235ac25a Cr50: Fix bug in print_later, add overflow detection
Oops. I was losing one of the args when the USB debugging output
was enabled. And with a lot of messages I was also losing some
of the output.

BUG=chrome-os-partner:34893
BRANCH=none
TEST=make buildall, manual test of Cr50 USB:

1. Plug into a USB jack on a Linux host.
2. In src/platform/ec/extra/usb_console, run

  make
  ./usb_console -p 5014 -e 1

3. Type something, hit return
4. See whatever you typed come back with swapped case
5. ^D to quit
