drm/amd/display: Fix incorrect DSC recompute trigger

[ Upstream commit 4641169a8c ]

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.
