drm/i915: Double check that the wait_request is not pending before warning

If we are busy, then we may have woken up the wait_request handler but
not yet serviced it before the hang check fires. So in hang check,
double check that the i915_gem_do_wait_request() is still pending the
wake-up before declaring all hope lost.

Fixes regression with e78d73b16bcde921c9cf458d2e4de8e4fc2518f3.
