hwcontext_d3d11va: allocate staging texture lazily

Makes dealing with formats that can not be used for staging textures
easier (DXGI_FORMAT_420_OPAQUE). It also saves memory if the staging
texture is never needed, so this is a good thing.

Merges Libav commit 98d73e4174333b37d961b79e1182be5a02156c02.
