RDMA/hns: Response dmac to userspace 

driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8HZ7W



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

While creating AH, dmac is already resolved in kernel. Response dmac
to userspace so that userspace doesn't need to resolve dmac repeatly.
