{rt, realtime, dl}_{task, prio}() functions return value is actually
a bool. Convert their return type to reflect that.

Nit: `return unlikely(prio < MAX_DL_PRIO)` would be simpler.
The same can be applied to rt_prio() and realtime_prio(). This would
make {dl, rt, realtime}_task() single-liner. Maybe further
simplification can be done.
