USB: serial: opticon: fix control-message timeouts
commit 5e28055f340275a8616eee88ef19186631b4d136 upstream.
The driver was issuing synchronous uninterruptible control requests
without using a timeout. This could lead to the driver hanging
on open() or tiocmset() due to a malfunctioning (or malicious) device
until the device is physically disconnected.
The USB upper limit of five seconds per request should be more than
enough.
