sched/deadline: Avoid double update_rq_clock()

sched/deadline: Avoid double update_rq_clock()

[ Upstream commit 4de9ff76067b40c3660df73efaea57389e62ea7a ]

When setup_new_dl_entity() is called from enqueue_task_dl() ->
enqueue_dl_entity(), the rq-clock should already be updated, and
calling update_rq_clock() again is not right.

Move the update_rq_clock() to the one other caller of
setup_new_dl_entity(): sched_init_dl_server().
