rockchip_drm_endpoint_is_subdriver() may also return error codes. For example if the target-node is in the disabled state, so no platform-device is getting created for it.

In that case current code would count that as external rgb device, which in turn would make probing the rockchip-drm device fail.

So only count the target as rgb device if the function actually returns 0.
