ovn: Don't fail db sync if new IP allocation fails for metadata

Browse Source 
There is a scenario where IP allocation pool is depleted but OVN
metadata port got removed its IP manually. The DB sync script will
attempt to allocate a new IP address if DHCP is enabled in the subnet.
Since the pool has no available IP addresses an exception is raised and
the whole db sync stops.

This patch simply catches the exception, logs and error and continues
syncing other resources.
