Subject: net/mlx5: Avoid disabling RoCE when uninitialized
Patch-mainline: v5.4-rc1
Git-commit: 3a6ef5158d4a01a2ddd88c3c978e6de0d10ee759
References: jsc#SLE-8464
Move the check if RoCE steering is initialized to the
disable RoCE function, it will ensure that we disable
RoCE only if we succeeded in enabling it before.
Fixes: 80f09dfc237f ("net/mlx5: Eswitch, enable RoCE loopback traffic")
