Subject: RDMA/hns: Rename wqe buffer related functions
Patch-mainline: v5.7-rc1
Git-commit: 6c6e39212b18bffd806423a45359c70221ce0d77
References: jsc#SLE-14777

There are serval global functions related to wqe buffer in the hns driver
and are called in different files. These symbols cannot directly represent
the namespace they belong to. So add prefix 'hns_roce_' to 3 wqe buffer
related global functions: get_recv_wqe(), get_send_wqe(), and
get_send_extend_sge().
