Subject: IB/mlx5: avoid excessive warning msgs when creating VFs on 2nd port
Patch-mainline: v4.19-rc1
Git-commit: 2577188edcf3e235b4f060a350fad84510eb7680
References: bsc#1103991 FATE#326007

When a CX5 device is configured in dual-port RoCE mode, after creating
many VFs against port 1, creating the same number of VFs against port 2
will flood kernel/syslog with something like
"mlx5_*:mlx5_ib_bind_slave_port:4266:(pid 5269): port 2 already
affiliated."

So basically, when traversing mlx5_ib_dev_list, mlx5_ib_add_slave_port()
repeatedly attempts to bind the new mpi structure to every device on the
list until it finds an unbound device.

Change the log level from warn to dbg to avoid log flooding as the warning
should be harmless.
