Take proper references for hw color blobs (degamma_lut, gamma_lut,
ctm, lut_3d) in intel_plane_duplicate_state() and drop them in
intel_plane_destroy_state().

Fixes: 3b7476e786c2 ("drm/i915/color: Add framework to program PRE/POST CSC LUT")
Fixes: a78f1b6baf4d ("drm/i915/color: Add framework to program CSC")
Fixes: 65db7a1f9cf7 ("drm/i915/color: Add 3D LUT to color pipeline")
