drm/i915: Add a warning on shutdown if signal threads still active

When unloading the module, it is expected that we have finished
executing all requests and so the signal threads should be idle. Add a
warning in case there are any residual requests in the signaler rbtrees
at that point.

v2: We can also warn if there are any waiters
