USB: serial: f81232: fix division by zero on line-speed change
commit a08ca6ebafe615c9028c53fc4c9e6c9b2b1f2888 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.
