Tejun Heo d94d09a233 sched_ext: When calling ops.dispatch() @prev must be on the same scx_sched ...

The @prev parameter passed into ops.dispatch() is expected to be on the
same sched. Passing in @prev which isn't on the sched can spuriously
trigger failures that can kill the scheduler. Pass in @prev iff it's on
the same sched.
