[PATCH 5.15 684/917] RDMA/hns: Fix initial arm_st of CQ

From: Haoyue Xu <redacted>

[ Upstream commit 571fb4fb78a3bf0fcadbe65eca9ca4ccee885af4 ]

We set the init CQ status to ARMED before. As a result, an unexpected CEQE
would be reported. Therefore, the init CQ status should be set to no_armed
rather than REG_NXT_CEQE.

Fixes: a5073d6054f7 ("RDMA/hns: Add eq support of hip08")
