You might need to add some checks here :

<script type="text/javascript">
		jQuery(document).ready(function(){
                    if( jQuery('form.acf-form').get(0) ){
                        jQuery('form.acf-form').append('<input type="hidden" name="acf[post_ID]" value="' + acf.o.post_id + '"/>');
			jQuery('form.acf-form').append('<input type="hidden" name="acf[frontend]" value="true"/>');
                    }
		});
</script>

You should be able to use the following :

add_action('admin_init', 'remove_menus');
function remove_menus(){
	if(!current_user_can('add_users')){
		remove_menu_page('jetpack');
	}
}
