ivtv: fix incorrect device_caps for ivtvfb
[ Upstream commit 25e94139218c0293b4375233c14f2256d7dcfaa8 ]
The VIDIOC_G_FBUF and related overlay ioctls no longer worked (-ENOTTY was
returned).
The root cause was the introduction of the caps field in ivtv-driver.h.
While loading the ivtvfb module would update the video_device device_caps
field with V4L2_CAP_VIDEO_OUTPUT_OVERLAY it would not update that caps
field, and that's what the overlay ioctls would look at.
It's a bad idea to keep information in two places, so drop the caps field
and only use vdev.device_caps.
