I am working on replacing with ib_cq_pool_get(), this need ib_poll_context
to indicate the poller which provides by ib_poll_handler(). It's okay
for now, but for the callback function. When it polled a ib_wc, it
would call wc->wr_cqe->done(cq, wc), which is the union with wr_id. The
wr_id is heavily used in SMC.

In this patch set, I am not going to change the logic which is out of cq
allocation. So I have to use original interface to allocate cq this
time.

I am glad to hear your advice, if I missed information or misunderstood.

Thanks,
Tony Lu
