[PATCH net-next 1/5] bonding: The fail_over_mac should be set only in ACTIVE_BACKUP mode

[Ding Tianhong <dingtianhong@huawei.com>]

According the bonding.txt, the option fail_over_mac only affect for
AB mode, but in currect code, the parameter could be set to active
or follow in every mode, this will cause bonding could not set all
slaves of an RR or XOR mode to the same MAC address at enslavement
time, so reset fail_over_mac to 0 if the mode is not ACTIVE_BACKUP.

Fix the wrong variables for pr_err().
