cfq_exit_queue() should cancel cfq_data->unplug_work
Spotted by Nick <gentuu@gmail.com>, perhaps explains the first trace in
http://bugzilla.kernel.org/show_bug.cgi?id=9180.
cfq_exit_queue() should cancel cfqd->unplug_work before freeing cfqd.
blk_sync_queue() seems unneeded, removed.
Q: why cfq_exit_queue() calls cfq_shutdown_timer_wq() twice?
