drm/amd/display: Do not update DRR while BW optimizations pending

Browse source

[why]
While bandwidth optimizations are pending, it's possible a pstate change
will occur.  During this time, VSYNC handler should not also try to update
DRR parameters causing pstate hang

[how]
Do not adjust DRR if optimize bandwidth is set.
