zebra: re-install static routes needed vrf when the vrf intf comes up

Problem reported that if the vrf device is taken down and then brought
back up, any static route referencing that vrf device was not
re-installed.  This fix runs back thru the static routes that
reference the vrf device coming up and re-install them.
