[FFmpeg-devel] [PATCH 1/3] avutil/hwcontext_d3d11va: remove check for d3d11 debug layer dll

[Timo Rothenpieler <timo@rothenpieler.org>]

At least on latest Win 11 and Visual Studio 2022, that DLL does not
exist anymore and can't be installed via any of the usual means.
However, debugging works just fine regardless, so this check makes
debugging impossible.

D3D11CreateDevice will fail anyway if debugging is not supported, so
let's rely on that instead.
