Sil Vilerino a9a2ddaea8 lavu/hwcontext_qsv: Update after adding support for VAAPI on Windows 
- qsv_internal.h: Remove unnecessary include va_drm.h
- qsv_internal.h: Enable AVCODEC_QSV_LINUX_SESSION_HANDLE on Linux/VA only
- hwcontext_qsv.c: Do not allow child_device_type VAAPI for Windows until
  support is added, keep D3D11/DXVA2 as more prioritary defaults.
