drm/msm/dpu: Wire up DSC mask for active CTL configuration

Active CTLs have to configure what DSC block(s) have to be enabled, and
what DSC block(s) have to be flushed; this value was initialized to zero
resulting in the necessary register writes to never happen (or would
write zero otherwise).  This seems to have gotten lost in the DSC v4->v5
series while refactoring how the combination with merge_3d was handled.
