wined3d: Don't try to access unused buffers in wined3d_context_gl_load_numbered_arrays().

wined3d_stream_info_from_declaration() doesn't update elements of the
stream_info structure that are not used by the current vertex
declaration. That means that there might be obsolete buffer references
in stream_info, possibly to buffers that have since been destroyed.
