This patch addresses the following warning spotted by
using coccinelle where the case checked does the same
than the else case.

drivers/gpu/drm/amd/display/dc/dml/dcn32/display_mode_vba_util_32.c:4664:8-10: WARNING: possible condition with no effect (if == else)

Fixes: 974ce181 ("drm/amd/display: Add check for PState change in DCN32")
