Subject: RDMA/hns: Set reset flag when hw resetting
Patch-mainline: v5.3-rc1
Git-commit: 726be12f5ca0a9b464e7d91add512071e4c224f6
References: bsc#1104427 FATE#326416

When hw resetting, there is no response from hw when driver sending cmdq.
If driver still send cmdq to hw, the reset process may be blocked.  So
reset flag should be set to intercept the cmdq command when driver
receiving "notify down" signal.
