sched/deadline: Avoid pointless __setscheduler()
There is no need to dequeue/enqueue and push/pull if there are
no scheduling parameters changed for the DL class.
Both fair and RT classes already check if parameters changed for
them to avoid unnecessary overhead. This patch add the parameters
changed test for the DL class in order to reduce overhead.
