[D3DCOMPILER_43] Addendum to last commit CORE-14955 & CORE-15652

GCC Linux build had no issues with the last commit but
MSVC x86 & x64 v18.0.31101.0 choked on it with
error C4133: 'function' : incompatible types - from 'D3D_PRIMITIVE *' to 'DWORD *'
and similar.

I could not retest with that exact version of MSVC, but the mentioned problems
vanished for me when compiling locally with MSVC 16.0.40219.1 x86.
Fingers crossed, that this makes the builders happy again!
