Subject: d3d11: change mp_image plane pointer semantics

Until now, the texture pointer was stored in plane 1, and the texture
array index was in plane 2. Move this down to plane 0 and plane 1. This
is to align it to the new WIP D3D11 decoding API in Libav, where we
decided that there is no reason to avoid setting plane 0, and that it
would be less weird to start at plane 0.
