Subject: [PATCH 2/2] drm/amd/display: Use kfree() to free rgb_user in calculate_user_regamma_ramp()

Use kfree() instead of kvfree() to free rgb_user in
calculate_user_regamma_ramp() because the memory is allocated with
kcalloc().

Looks like this kvfree is from merge conflict between 
1fafef9dfe12 ("Merge drm-fixes-for-v4.17-rc6-urgent into drm-next")
and 6396bb221514 ("treewide: kzalloc() -> kcalloc()").
I'm not adding cc to stable because the bug looks harmless. You can
squash the commits if you want.
