When comparing the bond-settings of an activated device against
the settings from the connection, some properties might easily
differ. Hack them around in NMSettingBond:compare_property().

For example:

the setting in the connection has:
    [bond]
    mode=active-backup

later, the device gets:
    [bond]
    active_slave=inf_ib0
    fail_over_mac=active
    mode=active-backup

Note that the fail_over_mac changes due to:
  kernel: nm-bond: enslaved VLAN challenged slave inf_ib0. Adding VLANs will be blocked as long as inf_ib0 is part of bond nm-bond
  kernel: nm-bond: The slave device specified does not support setting the MAC address
  kernel: nm-bond: Setting fail_over_mac to active for active-backup mode
