v1 took a simplistic approach:

but not specific enough according to the review. So adding some extra complexity of checking for specific errors and flag bits to "ignore" the error similar to the catch-all openflags VIR_STORAGE_VOL_OPEN_NOERROR for all the virStorageBackendUpdateVol{Info|TargetInfo|TargetInfoFD} API's which are used to get the volume capacity, allocation, etc. data.
Along the way an inavertent bug was found and fixed in patch 3 in virStorageBackendUpdateVolTargetInfo where an error could have been reported, but not propagated back to the user since 'ret' would have been 0 after the virStorageBackendUpdateVolTargetInfoFD call.
