drm/amd/display: unset initial value for tf since it's never used

Browse Source 
In mod_color_calculate_{degamma/regamma}_params(), a tf variable is
initialized as TRANSFER_FUNCTION_SRGB but tf is only used after tf =
input->tf, therefore, better to just remove this initial value and avoid
misleading interpretations.
