libcamera: v4l2_device: Log control id instead of errorIdx
v4l2_ext_controls.errorIdx (in the case of single failing control for
VIDIOC_*_EXT_CTRLS calls) represents the index of that control.
Since it is a single control, we can print the control id rather than
its index. This improves logging as the id can be easily co-related
with the controls while reading the log.
