Subject: [net V2 3/8] net/mlx5: E-Switch, Err when retrieving steering name-space fails

From: Or Gerlitz <ogerlitz@...lanox.com>

Make sure to return error when we failed retrieving the FDB steering
name space. Also, while around, correctly print the error when mode
change revert fails in the warning message.
