BUG/MINOR: debug: make "debug dev sched" accept a negative TID

The TID passed to "debug dev sched" is used to pin the task to a given
thread. A negative value normally means the task is unpinned and goes
to the shared wait queue and run queue. However due to the type of the
variable, negative values were mapped as highly positive values and were
set to the current thread. Let's add the proper cast to fix this.

No backport is needed since this is only used to experiment with the
scheduler and measure its performance.
