Subject: IB/mlx5: Move loopback initialization to the corresponding stage
Patch-mainline: v4.16-rc1
Git-commit: c8b8992446a945c103ac74ebd5e05672d9b3c48a
References: bsc#1103991 FATE#326007

The loopback stage only initializes a lock, move it to be in
the CAPS initialization phase and get rid loopback step completely.
