drm/sched: Drop suffix from drm_sched_wakeup_if_can_queue

drm/sched: Drop suffix from drm_sched_wakeup_if_can_queue

Because a) helper is exported to other parts of the scheduler and
b) there isn't a plain drm_sched_wakeup to begin with, I think we can
drop the suffix and by doing so separate the intimiate knowledge
between the scheduler components a bit better.
