maillist inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IARV1S CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git/commit/?id=39c...

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

There are several error cases where hns_roce_create_ah() returns directly without jumping to sw stat path, thus leading to a problem that the ah error counter does not increase.
