Bug in download main.yml

I think there was a mistake here:

"{{ peer_with_calico_rr is defined and peer_with_calico_rr }} and kube_network_plugin == 'calico'"

should be

"{{ peer_with_calico_rr is defined and peer_with_calico_rr and kube_network_plugin == 'calico' }}"

this is causing calico_rr to be download even if you are using something other than calico
