[PATCH 03/18] qemuBlockStorageSourceAttachData: Add field for ad-hoc storage node name

[Peter Krempa <pkrempa@xxxxxxxxxx>]

SCSI hostdevs don't have a virStorageSource associated with the backend
in certain cases. Adding a separate field to hold memory for a copy of
the nodename of the storage backend will allow reusing the blockdev
machinery also for SCSI hostdevs.
