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
