Subject: [PATCH] radeonsi/vcn : update enc->dpb ref_use for index 0

Currently dpb_enc referneces not updated properly when index 0, as
we are skipping clearing that ref.

This patch will fix this for index 0. So that when ever we set
non_referenced flag, that is not used as ref and not pushed to DPB.
This is helping in SVC encoding.
