#1487476 — [PATCH V2 for-next 09/19] IB/hns: Modify the init of iboe lock

From: Lijun Ou <oulijun@huawei.com>

This lock will be used in query port interface, and will be called
while IB device was registered to OFED framework/IB Core. So, the
lock of iboe must be initiated before IB device was registered.
