RDMA/mlx5: Fix state and counter desync on loopback enable failure

Browse source

In mlx5_ib_enable_lb(), dev->lb.enabled was unconditionally set
to true even if mlx5_nic_vport_update_local_lb() failed.

Fix this by only setting dev->lb.enabled on success. On failure,
roll back the reference counters and return the error.
