5d324dae11 dxva2_hevc: properly signal the num_delta_pocs from the SPS RPS 
ucNumDeltaPocsOfRefRpsIdx needs to contain the flat value from the SPS RPS,
and not the final computed value from the slice header RPS, as this calculation
is done internally by the driver again.

b9f76d19d8 hevc_ps: make sure failing to decode an SPS always returns an error 
Some of the goto err clauses do not set the error code. It seems better
to fall back on INVALIDDATA instead of adding it everywhere explicitly.
