nv50: use the no-mipmap texture type for 2d ms views
There are size restrictions on 2D images which can't accommodate the full 2D MSAA image. There's no way to make it work for 2D MSAA Array images, but at least for the non-array variants, we can use the no-mipmap variant which has a larger maximum size.
Fixes dEQP-GLES31.functional.shaders.builtin_functions.texture_size.*2d
