USB: serial: io_ti: fix div-by-zero in set_termios
commit 6aeb75e6adfaed16e58780309613a578fe1ee90b upstream.
Fix a division-by-zero in set_termios when debugging is enabled and a
high-enough speed has been requested so that the divisor value becomes
zero.
Instead of just fixing the offending debug statement, cap the baud rate
at the base as a zero divisor value also appears to crash the firmware.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
