Subject: [PATCH] avutil/hwcontext_d3d12va: wait the texture is used inside the
GPU before to free it.

fix: ID3D12Resource2::<final-release>: CORRUPTION: An ID3D12Resource object (0x00000222D58B5450:'Unnamed Object') is referenced by GPU operations in-flight on Command Queue (0x00000222EEC87090:'Unnamed ID3D12CommandQueue Object').
     It is not safe to final-release objects that may have GPU operations pending.  This can result in application instability. [ EXECUTION ERROR #921: OBJECT_DELETED_WHILE_STILL_IN_USE]
