This commit removes the follow warning and error:

D3D12 WARNING: ID3D12CommandList::ResourceBarrier: Called on the same subresource(s) of
Resource(0x000002236E0E00D0:'Unnamed ID3D12Resource Object') in separate Barrier Descs
which is inefficient and likely unintentional. Desc[0] and Desc[1] on (subresource :
4294967295). [RESOURCE_MANIPULATION WARNING #1008: RESOURCE_BARRIER_DUPLICATE_SUBRESOURCE_TRANSITIONS]

D3D12 ERROR: ID3D12CommandList::ResourceBarrier: Before state (0x0: D3D12_RESOURCE_STATE_[COMMON|PRESENT])
of resource (0x000002236E0E00D0:'Unnamed ID3D12Resource Object') (subresource: 0) specified
by transition barrier does not match with the state (0x20000: D3D12_RESOURCE_STATE_VIDEO_DECODE_WRITE)
specified in the previous call to ResourceBarrier [RESOURCE_MANIPULATION ERROR #527:
RESOURCE_BARRIER_BEFORE_AFTER_MISMATCH]
