UPSTREAM: workqueue: Remove now redundant lock acquisitions wrt. workqueue flushes

The workqueue code added manual lock acquisition annotations to catch
deadlocks.

After lockdepcrossrelease was introduced, some of those became redundant,
since wait_for_completion() already does the acquisition and tracking.

Remove the duplicate annotations.
