drm/i915: Disable waitboosting for fence_wait()
We want to restrict waitboosting to known process contexts, where we can
track which clients are receiving waitboosts and prevent excessive power
wasting. For fence_wait() we do not have any client tracking and so that
leaves it open to abuse.
v2: Hide the IS_ERR_OR_NULL testing for special clients
