[PATCH] nouveau: use proper atomic accessor to get crtc state

[Dave Airlie <airlied@gmail.com>]

From: Dave Airlie <airlied@redhat.com>

This gets the crtc state from the current state, instead of
trying to lookup or create a state.

atomic core started warning about this recently.

Fixes: 0a0e79a2d9ed ("drm/atomic: WARN about invalid drm_foo_get_state() usage")
