zebra: Allow v4 or v6 addresses to be optional after `vrf X` in show ip nht

The `show ip nht vrf EVA ...` command was not allowing you to only
specify the vrf anymore.  Fix this:

robot# show ip nht vrf EVA
  <cr>
  A.B.C.D   IPv4 Address
  X:X::X:X  IPv6 Address
robot# show ip nht vrf EVA 4.5.6.7
robot# show ip nht vrf EVA
robot#
