Neutron: only do ARP_CMD if IP_BRD is not an empty string

Some third party CI systems leave PUBLIC_INTERFACE as the default,
but do not actually create the device. ip would set errno to 1 when
this happens[1], and that's fine - however arping would exit with errno
set to 2, which triggers the exit_trap and stops stacking.[2]
