[PATCH rdma-core 7/7] libhns: Return correct value of cqe num when flushing cqe failed

[Weihang Li <liweihang@hisilicon.com>]

From: Yangyang Li <liyangyang20@huawei.com>

When flushing cqe failed, it will return a error code to
hns_roce_v2_poll_one() and no longer update cqe number which is necessary
for ULPs, that will lead to a process suspension.
Because error code of flush cqe is meaningless for ULPs, so we delete it.

Fixes: 321ec6d04c0b ("libhns: Package for polling cqe function")
