[PATCH pve-network 12/15] api: sdn: allow EVPN zones as fabric VRFs

[Gabriel Goller <g.goller@proxmox.com>]

Accept EVPN zones as the VRF provider for BGP and OSPF fabrics. EVPN zones
always have a dedicated VRF, so only simple zones need the default-vrf check.

Use a generic validation error and API description now that fabric VRFs are
not limited to simple zones.
