Subject: RDMA/hns: Limit scope of hns_roce_cmq_send()
Patch-mainline: v5.2-rc1
Git-commit: e95e52a1788d4a8af547261875c0fbae2e6e3028
References: bsc#1104427 FATE#326416

The forgotten static keyword causes to the following error to appear while
building HNS driver. Declare hns_roce_cmq_send() to be static function to
fix this warning.

drivers/infiniband/hw/hns/hns_roce_hw_v2.c:1089:5: warning: no previous
prototype for _hns_roce_cmq_send_ [-Wmissing-prototypes]
 int hns_roce_cmq_send(struct hns_roce_dev *hr_dev,
