Subject: RDMA/core: Follow correct unregister order between sysfs and cgroup
Patch-mainline: v4.20-rc1
Git-commit: c715a39541bb399eb03d728a996b224d90ce1336
References: bsc#1103992 FATE#326009

During register_device() init sequence is,
(a) register with rdma cgroup followed by
(b) register with sysfs

Therefore, unregister_device() sequence should follow the reverse order.
