Pull scheduler fixes from Borislav Petkov:
- Fix a performance regression when measuring the CPU time of a thread
(clock_gettime(CLOCK_THREAD_CPUTIME_ID,...)) due to the addition of
PSI IRQ time accounting in the hotpath
- Fix a task_struct leak due to missing to decrement the refcount when
the task is enqueued before the timer which is supposed to do that,
expires
- Revert an attempt to expedite detaching of movable tasks, as finding
those could become very costly. Turns out the original issue wasn't
even hit by anyone
