Subject: [PATCH] dxva2: include dxva.h if found
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Apparently, some build environments require dxva.h even for dxva2,
while others lack this header entirely.  Including it conditionally
allows building in both cases.
