rbd: discard not found error from GetMetadata

Browse Source 
During ResyncVolume call, discard not found
error from GetMetadata API. If the image gets
resynced the local image creation time will be
lost, if the key is not present in the image
metadata then we can assume that the image is
already resynced.
