sched/fair: Remove cfs_rq_tg_path() 

cfs_rq_tg_path() is used by a tracepoint-to traceevent (tp-2-te)
converter to format the path of a taskgroup or autogroup respectively.
It doesn't have any in-kernel users after the removal of the
sched_trace_cfs_rq_path() helper function.

cfs_rq_tg_path() can be coded in a tp-2-te converter.

Remove it from kernel/sched/fair.c.
