[autotest] Remove per-tick process restriction.
The per-tick process restriction was causing a performance problem
when a tick took a long time, and there isn't a good reason to keep
the per-tick process constraint as there is already a total process
constraint.
TEST=Ran the scheduler. The unit tests pass.
