drm/atomic: Convert drm_atomic_get_crtc_state() to use new connector state

The drm_atomic_get_crtc_state() function calls the deprecated
drm_atomic_get_existing_crtc_state() helper to get find if a crtc state
had already been allocated and was part of the given drm_atomic_state.

At the point in time where drm_atomic_get_crtc_state() can be
called (ie, during atomic_check), the existing state is the new state
and drm_atomic_get_existing_crtc_state() can thus be replaced by
drm_atomic_get_new_crtc_state().
