[PATCH] sched: fix outdated comment on task_prio() return value

[Antoine Busque <abusque@efficios.com>]

The comment describing the possible return values of the task_prio()
function, having not been updated in many years, was misleading. It
indicated an offset of -200 for RT tasks, and normal tasks having 32
possible priority values centered around 0. This is no longer the
case, as the values it returns will be in the range [-100..39]. The
new comment reflects the current behaviour.
