drm/i915: Revert 'guc_id' from i915_request tracepoint

Avoid adding backend specific data to the tracepoints outside of
the LOW_LEVEL_TRACEPOINTS kernel config protection. These bits of
information are bound to change depending on the selected submission
method per platform and are not necessarily possible to maintain in
the future.
