sched/deadline: Fix schedstats vs deadline servers
In dl_server_start(), when schedstats is enabled, the following
happens:
dl_server_start()
dl_se->dl_server = 1;
enqueue_dl_entity()
update_stats_enqueue_dl()
__schedstats_from_dl_se()
dl_task_of()
BUG_ON(dl_server(dl_se));
Since only tasks have schedstats and internal entries do not, avoid
trying to update stats in this case.
