IB/ehca: Refactor sync between completions and destroy_cq using atomic_t
- ehca_cq.nr_events is made an atomic_t, eliminating a lot of locking.
- The CQ is removed from the CQ idr first now to make sure no more
completions are scheduled on that CQ. The "wait for all completions to
end" code becomes much simpler this way.
