[ovs-dev] [PATCH ovn] pinctrl: Handle service monitors even if the lport doesn't have IPv4 addresses set.

[numans at ovn.org]

From: Numan Siddique <numans at ovn.org>

If a logical port is only configured with MAC address(es) in the
Logical_Switch_Port.addresses, pinctrl is ignoring the service monitors
configured for that logical port. This patch allows that.
