zebra: Don't display the vrf if not using namespace based vrfs

Currently when doing a `show ip route table XXXX`, zebra is displaying the current default vrf as the vrf we are in. We are displaying a table not a vrf. This is only true if you are not using namespace based vrf's, so modify the output to display accordingly. Signed-off-by: Donald Sharp <[email protected]>
