drm/nouveau/dispnv50: Don't call drm_atomic_get_crtc_state() in prepare_fb

Browse source

commit 560271e10b upstream.

Since we recently started warning about uses of this function after the
atomic check phase completes, we've started getting warnings about this in
nouveau. It appears a misplaced drm_atomic_get_crtc_state() call has been
hiding in our .prepare_fb callback for a while.

So, fix this by adding a new nv50_head_atom_get_new() function and use that
in our .prepare_fb callback instead.
