[PATCH V2] drm/amd/display: correct idle_power_optimizations disablement return value

[PATCH V2] drm/amd/display: correct idle_power_optimizations disablement return value

[Evan Quan]

[Why]
The return value indicates whether the operation(disable/enable) succeeded
or not. The existing logic reports wrong result even if the disablement was
performed successfully. That will make succeeding reenablement abandoned
as dc->idle_optimizations_allowed is always true.

[How]
Correct the return value to reflect the real result of disablement.
