update the capacity to zero on shutdown/reset

When the device plugin is restarted, kubelet marks the resource as unhealthy, but still reports the resource as existing for a grace period (5 mins). If a pod is scheduled before the device plugin comes up, the pod create fails without a retryloop with an error message Pod was rejected: Allocate failed due to no healthy devices present; cannot allocate unhealthy devices <DEVICE_NAME>, which is unexpected.

This commit allow the device plugin to send an empty list of devices before the reset or shutdown
