drm/amd/display: remove useless if/else
Fix the following coccinelle report:
./drivers/gpu/drm/amd/display/dc/calcs/dce_calcs.c:1367:3-5:
WARNING: possible condition with no effect (if == else)
Both branches are the same, so remove the if/else altogether.
Fixes: 81875979f0b2 ("drm/amd/display: Remove extra pairs of parentheses in dce_calcs.c")
