sched: Deadline has dynamic priority
While FIFO/RR have static priority, DEADLINE is a dynamic priority
scheme. Notably it has static priority -1. Do not assume the priority
doesn't change for deadline tasks just because the static priority
doesn't change.
This ensures DL always sees {DE,EN}QUEUE_MOVE where appropriate.
