[Intel-gfx] [PATCH 6/8] drm/i915/tracepoints: Rename i915_gem_request_notify

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
i915_gem_ring_notify is more appropriate since we do not have
the request information at this point, but it is simply a
signal from the engine that some request has been completed.
v2:
* Always trace and log if there were any waiters.
* Rename to intel_engine_notify. (Chris Wilson)
