[libvirt] [REPOST PATCH v6 1/8] conf, qemu: Replace iscsisrc fields with virStorageSourcePtr

Rather than picking apart the two pieces we need/want (path, hosts, and auth)- let's allocate/use a virStorageSourcePtr for iSCSI storage. The end result is that qemuBuildSCSIiSCSIHostdevDrvStr doesn't need to "fake" one for the qemuBuildNetworkDriveStr call.
