[PATCH network 2/2] api: vnets: assert vnet zone exists on create and update

[Daniel Kral <d.kral@proxmox.com>]

If a VNet is created or updated with an empty zone '' or a non-existing
zone identifier, the API handler will die with a slighly confusing error
message:

create sdn vnet object failed: cannot lookup undefined type! at
/usr/share/perl5/PVE/API2/Network/SDN/Vnets.pm line 326.

Therefore, use the helper sdn_zones_config(), which asserts whether the
zone identifier is non-empty and existing.
