[pve-devel] [PATCH container] fix creating unmanaged containers

$keynames was not a hash reference since nothing was returned by
ssh_host_key_types_to_generate for unmanaged containers, this causes the
post_create_hook to fail and no container is created.

fix by returning an empty hash so that $keynames can be a hashref and
processed accordingly.

also dropped a remaining unmanaged return (should have no effect anymore
anyways, since $self->{plugin} is now set to 'unmanaged' instead of
empty)

---

note that we can still allow generating ssh keys for unmanaged
containers, i have another patch like that (i can send if you wish),
which doesn't skip creating ssh keys -- however for that to work we need
to use functions from PVE::Tools (so that we can have ct_file_exists and
friends)
