csi: missing plugins during node delete are not an error (#8619)

Browse Source 
When deregistering a client, CSI plugins running on that client may not get a
chance to fingerprint before being stopped. Account for the case where a
plugin allocation is the last instance of the plugin and has been deleted from
the state store to avoid errors during node deregistration.
