sched: tg->se->load should be initialised to tg->shares
Michael reported that when enable autogroup on UP, system
responsiveness becomes very bad.
Because in init_tg_cfs_entry() we initialise se->load
to 0 instead of tg->shares, in the end we have 0-weight
sched entity on rq, then lead to misbehavior.
