Excluded changes with std::atomic (C++98 requirement)

Currently the private control enumeration will be stopped when QUERYCTRL
returns -EINVAL only. It is possible however that other errors occur.

One particular case is when the v4l2 device doesn't support any controls
and doesn't implement the QUERYCTRL ioctl. In that case the v4l2
framework returns -ENOTTY. In that case the current control enumeration
will go in an endless loop.

To fix this change the control enumeration stop condition. If any errors
occur, end the control enumeration.
