We might be willing to call intel_atomic_get_old_global_obj_state
and intel_atomic_get_new_global_obj_state right away, however
those are not initializing global obj state as
intel_atomic_get_global_obj_state does.
Extracted initializing part to separate function and now using this
also in intel_atomic_get_old_global_obj_state and intel_atomic_get_new_global_obj_state

v2: - Fixed typo in function call
