"An outstanding request must still be on an active ring somewhere" is
only true if we haven't just been interrupted by the shrinker in the
middle of allocating the request itself. (At the start of
i915_request_alloc() we pin the context and prepare the GT for activity,
marking it as active, and then try to allocate the request. If this
allocation invokes the shrinker, we try to reclaim some space by calling
i915_retire_requests() which may then be confused by the pre-reservation
of active_requests.)

Note that the oops here is actually of any allocation after
i915_request_alloc and before i915_request_add. To close that coarse
window, we could move the list_add(rq, ring->request_list) to
i915_request_alloc, but we still have the issue of the allocations inside
i915_request_alloc itself.
