[PATCH 2/9] virStorageFileGetMetadataRecurse: Remove impossible error report

[Peter Krempa <pkrempa@xxxxxxxxxx>]

We call virStorageFileSupportsBackingChainTraversal which already checks
that the 'storageFileRead' callback is non-NULL, which in turn means
that virStorageFileRead will not return -2.
