Wrapping a kfree is pointless.
v2: Add a comment to the kerneldoc for drm_agp_init to explain where
the kfree happens as requested by David. Note that for modeset drivers
agp cleanup is fairly complicated anyway: The drm_agp_clear is a noop
and drivers must call drm_agp_release on their own. Which they all
seem to do properly.
