drm/amd/display: Proper return of result when aux engine acquire fails
[Why]
When aux engine acquire fails, we missed populating the operation_result
that describes the failure reason.
[How]
Set operation_result to new type:
AUX_CHANNEL_OPERATION_FAILED_ENGINE_ACQUIRE
in the case aux engine acquire has failed.
