trace/sched: set priority to 150 for deadline tasks

Browse Source 
As deadline tasks doesn't have priority, their priority is set
to -1. If there are any deadline tasks in the system, chrome/tracing
doesn't show results as expected as it can't recognize tasks with
priority -1. Fix it by using 150 as priority for deadline tasks.
