Gabriel Krisman Bertazi 415d3dab96 blk-mq: Drop explicit timeout sync in hotplug
After commit 287922eb0b18 ("block: defer timeouts to a workqueue"),
deleting the timeout work after freezing the queue shouldn't be
necessary, since the synchronization is already enforced by the
acquisition of a q_usage_counter reference in blk_mq_timeout_work.
