multus-cni manifests template error or docs error

[pepesi]

What happened:
I used the nicclusterpolicy in the example

https://github.com/Mellanox/network-operator/blob/master/example/crs/mellanox.com_v1alpha1_nicclusterpolicy_cr.yaml

but got empty cni config file '00-multus.conf'.

After google it, got this document
https://docs.nvidia.com/networking/display/cokan10/network+operator#src-39285883_NetworkOperator-MultusCNI

It says "Multus CNI config. If empty, the config will be automatically generated from the CNI configuration file of the master plugin (the first file in lexicographical order in the cni-confg-dir)."

network-operator/example/crs/mellanox.com_v1alpha1_nicclusterpolicy_cr.yaml

Line 68 in 49e9bea

config: ''

Finally, NodeNotReady with error "cni plugin not initialized", and the 00-multus.conf is an empty file.

What you expected to happen:
I hope it can work normally

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:

network-operator/manifests/state-multus-cni/0050-multus-ds.yml

Line 51 in 49e9bea

- "--multus-conf-file={{- if .CrSpec.Config -}}/tmp/multus-conf/00-multus.conf{{- else -}}auto{{- end -}}"

change this line

{{- if .CrSpec.Config -}}{{- if gt (len .CrSpec.Config) 0 -}}/tmp/multus-conf/00-multus.conf{{- else -}}auto{{- end -}}{{- else -}}auto{{- end -}}
