drm/i915/execlists: Record preemption for selftests
Put back the preemption counters lost in commit 22b7a426bbe1
("drm/i915/execlists: Preempt-to-busy") so that our selftests that
assert no preemption took place continue to function.
v2: But a timeslice is only a "soft" preemption!
Fixes: 22b7a426bbe1 ("drm/i915/execlists: Preempt-to-busy")
