Ok, that makes sense. You won't be able to just free requests that are
pending in the OCF layer. There is no cancel option.
Once a request has been handed to OCF you will need to wait for OCF to
complete it. It could be tied up in the actual crypto driver or
waiting in an OCF queue.
Your driver close routine should wait for pending requests to complete
before allowing the unload.
