sched: uninline __enqueue_entity()/__dequeue_entity()

suggested by Roman Zippel: uninline __enqueue_entity() and
__dequeue_entity().

this reduces code size:

      text    data     bss     dec     hex filename
     25385    2386      16   27787    6c8b sched.o.before
     25257    2386      16   27659    6c0b sched.o.after
