[ Upstream commit 4641169a8c95d9efc35d2d3c55c3948f3b375ff9 ]
A stream without dsc_aux should not be eliminated from the dsc determination. Whether it needs a dsc recompute depends on whether its mode has changed or not. Eliminating such a no-dsc stream from the dsc determination policy will end up with inconsistencies in the new dc_state when compared to the current dc_state, triggering a dsc recompute that should not have happened.
