Chris Wilson 6cb0c6ad9e drm/i915/shrinker: Wrap need_resched() inside preempt-disable
In order for us to successfully detect the end of a timeslice,
preemption must be disabled. Otherwise, inside the loop we may be
preempted many times without our noticing, and each time our timeslice
will be reset, invalidating need_resched()
