On return from S3 the driver may receive failure when
calls DxgkCbAcquirePostDisplayOwnership. In general the
driver is not expected to use this method when returns
from S3 but it is not simple to distinguish between S3
and S4 power transition (possible, due to hybrid sleep).
Current commit avoids returning error on power transition
and obtains best known default video mode info instead.
