zebra: Reconfiguring netns for vrf is not a failure

When using namespace VRF backend, and frr.conf contains:

    vrf test
      netns /run/netns/test
    exit-vrf

FRR fails to start:

    line 11: Failure to communicate[13] to zebra, line:  netns /run/netns/test

Fix this by returning CMD_WARNING rather than CMD_WARNING_CONFIG_FAILED
when the same netns path is configured.
