Aaron Levinson	7793fc5b33	avutil/hwcontext_dxva2: Don't improperly free IDirect3DSurface9 objects Add dxva2_pool_release_dummy() and use it in call to av_buffer_create() in dxva2_pool_alloc(). Prior to this change, av_buffer_create() was called with NULL for the third argument, which indicates that av_buffer_default_free() should be used to free the buffer's data. Eventually, it gets to buffer_pool_free() and calls buf->free() on a surface object (which is av_buffer_default_free()). This can result in a crash when the debug version of the C-runtime is used on Windows. While it doesn't appear to result in a crash when the release version of the C-runtime is used on Windows, it likely results in memory corruption, since av_free() is being called on memory that was allocated using IDirectXVideoAccelerationService::CreateSurface().
