Subject: RDMA/hns: Use delay instead of usleep
Patch-mainline: v4.19-rc1
Git-commit: 73b4e1f4c04e76b19fca296d09b97555bfb35202
References: bsc#1104427 FATE#326416
In order to avoid using usleep function in lock function, we use delay
function instead of it. Besides, it also use brackets for standardized
the computed order.
