[PATCH 2/2] qemuBuildHostdevSCSIAttachPrepare: Propagate 'readonly' flag also for iSCSI

[Peter Krempa]

The 'readonly' hostdev property is stored separately from the
virStorageSource as some hostdevs are not described by a virStorage
source. We need to propagate the flag to the virStorage source also for
iSCSI backends as it's used to generate the backend properties.
