Public bug reported:

There looks to be a window when a port is being created that has
requested fixed IPs on specific subnets where the subnet can be deleted
and the port creation will return successfully without getting IPs on
all requested subnets.

This interferes with the DHCP agent which expects to get IPs on the
subnets it requests or an exception indicating that a subnet does not
exist.

This is likely related to the fact that we allow automatic cascade
deletes in our IP allocation data model when a subnet is deleted.
