    Not set fip to ERROR if it exists on device
    
    The centralized floating IP can exist on the router device
    due to some reasons like: uncleaned fip addr, and especially
    multiple IP addr adding action: HA router _add_vip() and
    Edge router add_ip_address().
    This patch catches the IpAddressAlreadyExists error if fip
    was already set on the device, and still process next step.
