Alex Hung f82097e0cd drm/amd/display: Validate hw_points_num before using it
[ Upstream commit 58c3b3341cea4f75dc8c003b89f8a6dd8ec55e50 ]

[WHAT]
hw_points_num is 0 before ogam LUT is programmed; however, function
"dwb3_program_ogam_pwl" assumes hw_points_num is always greater than 0,
i.e. substracting it by 1 as an array index.

[HOW]
Check hw_points_num is not equal to 0 before using it.
