device: some v4l2 cameras do not accept parameters unless streaming

Browse Source 
This fixes 3DO camera not accepting `--camera-options=focus_absolute=100`
and `--camera-options=focus_automatic_continuous=0`, and not properly
configuring the sensor.

The settings are applied twice (if failed) to ignore ordering problems
related to auto-focus and focus-absolute value command line order.
