We can return WINED3DOK_NOAUTOGEN only when all other resource usages
are supported.

Fixes 25a8773d ("wined3d: Advertise AUTOGENMIPMAP only for
renderable and filterable formats."). The problem was present before
25a8773d, but the mentioned commit made it much worse. Previously,
it was an issue only for OpenGL implementations which do not support
the GL_SGIS_generate_mipmap extension.
