Thanks for spotting, fixed!

Correct, so I have done few changes here and for DSC block reservation..
- Calling dpu_rm_get_assigned_resources() for DSC only when DSC is
  required from dpu encoder
- moved the above code to dsc helper: _dpu_rm_reserve_dsc() as suggested
  by Abhinav as well
- Check if DSC is supported and then check if DSC 0|1 are not allocated
  and then assign as above
