media: usbtv: fix control-message timeouts
The driver was issuing synchronous uninterruptible control requests
without using a timeout. This could lead to the driver hanging on
various user requests 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.

Fixes: c53a846c48f2 ("[media] usbtv: add video controls")
