This fixes two bugs in anim_utils.py that make bake_action unuseable:

1. bake_action refers to do_pose and do_object as though they are regular args rather than **kwargs, resulting in NameError: name 'do_pose' is not defined
2. bake_action_objects passes frames as a positional parameter when it is defined as a keyword-only parameter, resulting in TypeError: bake_action_objects() takes 1 positional argument but 2 were given
