Johan Hovold c0815ea085 USB: serial: f81534: fix division by zero on line-speed change
commit 188c9c2e0c 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.

Fixes: 3aacac02f3 ("USB: serial: f81534: add high baud rate support")
