[PATCH] drm/plane: Fix IS_ERR() vs NULL bug drm_plane_create_color_pipeline_property()

[Dan Carpenter <dan.carpenter@linaro.org>]

The drm_property_create_enum() function returns NULL on error, it never
returns error pointers.  Fix the error checking to match.

Fixes: 2afc3184f3b3 ("drm/plane: Add COLOR PIPELINE property")
