drm/amd/display: skip error logging when DMUB is inactive from S3

Browse Source 
[Why]
On resume from S3, while DMUB is inactive, DMUB queue and execute
calls will not work.  Skip reporting errors in these scenarios

[How]
Add new return code during DMUB queue and execute calls when DMUB
is in S3 state. Skip logging errors in these scenarios
