    sched: Uninline css_tg()
    
    Compilation with custom config fails:
    
    kernel/ve/ve.c: In function ‘ve_get_cpu_avenrun’:
    kernel/ve/ve.c:1679:27: error: inlining failed in call to always_inline ‘css_tg’: function body not available
     inline struct task_group *css_tg(struct cgroup_subsys_state *css);
                               ^~~~~~
    kernel/ve/ve.c:1690:7: note: called from here
      tg = css_tg(css);
           ^~~~~~~~~~~
    
    We may remove "inline" attribute, as compiler is clever enough
    to make itself inlining in kernel/sched/sched.c.
    
    To_merge: 90368f957e01 ("ve/sched/stat: Introduce functions to calculate
    vcpustat data")
