Johan Hovold 68fbe268d2 USB: serial: f81232: fix division by zero on line-speed change 
commit a08ca6ebaf upstream.

The driver leaves the line speed unchanged in case a requested speed is
not supported. Make sure to handle the case where the current speed is
B0 (hangup) without dividing by zero when determining the clock source.
