Changelog: Avoid a segfault in IWineD3DDeviceImpl_ProcessVertices by checking
if SrcImpl (parameter pVertexDecl) is NULL.
The function is called from dlls/d3d8/device.c
IDirect3DDevice8Impl_ProcessVertices with an explicit NULL as vertex
declaration parameter.
Crash was observed in Age of Mythology Trial.
