Revert "net: remove zap_completion_queue"

This reverts commit bf17ab2ee5df7e232112385ef1434b80afd01194.

As explained by Johannes Berg, the optimization made here is
invalid.  Or, at best, incomplete.

Not only destructor invocation, but conntract entry releasing
must be executed outside of hw IRQ context.

So just checking "skb->destructor" is insufficient.
