conf,qemu: Replace iscsisrc fields with virStorageSourcePtr

Browse Source 
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.
