After opening the device, the first thing we should do is selecting the
input. This is because the image formats (VIDIOC_ENUM_FMT ioctl) and the
standards (VIDIOC_ENUMSTD ioctl) supported may depend on the selected
input ([1] and [2]).

Make device_try_init() return an error value, and allow to properly
report errors which are not due to a wrong pixel/codec configuration.

In particular, report intelligible feedback in case of busy device.

The options have been deprecated and are non-operational since more than
two years.
