----------------------------------------------------------------------

When roce driver is removed during reset, the reset flow of roce may not be fully completed. This may lead to the reset_state of roce handler stored in nic driver remaining in a middle state, such as HNS_ROCE_STATE_RST_DOWN or HNS_ROCE_STATE_RST_UNINIT.

The reset_state won't be cleared even if roce driver is re-inited. This cause that roce bonding which currently relies on reset_state fails in this case.

Replace the reset detection for bonding with nic APIs (.ae_dev_resetting() and .get_hw_reset_stat()), just like the reset detection elsewhere in roce driver.

Commit 1470b68f21c3 ("RDMA/hns: Fix print after query hw id failed.") was meant to avoid error printing when HNS_ROCE_OPC_QUERY_HW_ID cmd is not supported, that is, when CMD_NOT_EXIST error is returned by FW.

But the checking condition is incorrect. Now all errors printings of HNS_ROCE_OPC_QUERY_HW_ID, even if the error code is not CMD_NOT_EXIST, will be ignored.

This cmd is for stars mode and cnp priority setting. Since this two features are supported only by HIP10, don't send this cmd on other platform.
