Subject: RDMA/hns: Move the location for initializing tmp_len
Patch-mainline: v4.17-rc7
Git-commit: 55ba49cbcef37053d973f9a45bc58818c333fe13
References: bsc#1104427 FATE#326416
When posted work request, it need to compute the length of
all sges of every wr and fill it into the msg_len field of
send wqe. Thus, While posting multiple wr,
tmp_len should be reinitialized to zero.
Fixes: 8b9b8d143b46 ("RDMA/hns: Fix the endian problem for hns")
