 'cwe': ['CWE-369'], 'message': 'USB: serial: io_ti: fix div-by-zero in set_termios

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.
