Christoph Hellwig c41108049d kyber: avoid q->disk dereferences in trace points 
q->disk becomes invalid after the gendisk is removed.  Work around this
by caching the dev_t for the tracepoints.  The real fix would be to
properly tear down the I/O schedulers with the gendisk, but that is
a much more invasive change.
