The global vrf in zebra is always non-NULL. In general, it is bound to default vrf by `zebra_vrf_init()`, at other times bound to some specific vrf. Anyway, non-NULL. So remove all redundant checkings for the returned value of `zebra_vrf_get_evpn()`. Additionally, remove the unnecessary check for `zvrf` in `zebra_vxlan_cleanup_tables()`.
