[libvirt] [PATCH 1/3] iscsi: Check for presence of error before creating new one
If virStorageBackendSCSIFindLUs fails, but the failure has an error
message - the iscsi code didn't honor that creating it's own wonderful
message such as "error: Failed to find LUs on host 60: ..." - not overly
helpful. Since a few of the called paths generate a message, check for
that before using that generic one.
