[PATCH network] sdn: fabrics: make ip_prefix and ip6_prefix deletable

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

This allows us to update (and remove) the prefixes of fabrics which
don't have any nodes configured. There still has to be at least one ipv6
or ipv4 prefix on the fabric. This is validated in the frontend and in
the backend (rust).
