IB/core: Protect against self-requeue of a cq work item

Browse source

[ Upstream commit 86f46aba8d ]

We need to make sure that the cq work item does not
run when we are destroying the cq. Unlike flush_work,
cancel_work_sync protects against self-requeue of the
work item (which we can do in ib_cq_poll_work).
