[PATCH v2 20/24] drm/amd/display: Fix shaper using bad LUT params

[Roman.Li]

From: Ilya Bakoulin <ilya.bakou...@amd.com>

[Why]
LUT params are not cleared after setting blend TF, which can lead to
same params being used for the shaper, if the shaper func is bypassed.

[How]
Set lut_params to NULL after program_1dlut.
