Revert "[ovn-controller] Don't create ovn-controller if nicMappings empty"

This reverts commit a02a159.

This change created a bug on the adoption where all the gates reaches TIME_OUT,
reverting this patch to unblock prod chain while fixing it.

The problem that this patch was introducing was that edpm deployment expects
a config map created by ovn-operator (ovncontroller) called ovncontroller-config.
With this patch the ovncontroller CR was not created and the ovn-operator was
not reconciling this object, which was needed to create the said config map.
