api: create_vm: check serial and usb permissions

Browse Source 
The existing check_vm_modify_config_perm doesn't do so anymore, but
the check only got re-added to the modify/delete paths. See commits
165be267eb and
e30f75c571 for context.

In the future, it might make sense to generalise the
check_vm_modify_config_perm and have it not only take keys, but both
new and old values, and use that generalised function everywhere.
