Juri Lelli a3d85c1489 sched/deadline: Fix replenish_dl_new_period dl_server condition 
commit 22368fe1f9 upstream.

The condition in replenish_dl_new_period() that checks if a reservation
(dl_server) is deferred and is not handling a starvation case is
obviously wrong.

Fix it.

Fixes: a110a81c52 ("sched/deadline: Deferrable dl server")
