rbd: discard image not found error

For flatten we call checkImageChainHasFeature
which internally calls to getImageInfo returns
the parent name even if the parent is in the trash,
when we try to open the parent image to get its
information it fails as the image not found.
we should treat error as nil if the parent is not found.
