[PATCH 3/5] wined3d: Require FBO attachability for render targets and depth stencils.

[Stefan Dösinger]

WINED3DFMT_NULL needs special handling in some form. Alternatively to
the solution I used we can handle it in resource_init or in the if check
that aborts init_format_fbo_compat_info / check_fbo_combat when a zero
internal format is used.
