v4l2: camera_proxy: Align trace message style

Most of the ioctl handlers in the V4L2CameraProxy class have an empty
line between the tracing printouts and the immediately following buffer
type validation. Align the two occasions where such an empty line is missing
with the others.

Cosmetic change only.
