powerpc/gamecube/wii: Fix off-by-one error in ugecon/usbgecko_udbg
The retry logic in ug_putc() is broken.
If the TX fifo is not ready and the counter runs out it will have a
value of -1 and no transfer should be attempted. Also, a counter
with a value of 0 means that the TX fifo got ready in the last try
and the transfer should be attempted.
