Re: [PATCH v2 7/9] qemu: Move <hostdev> SCSI path generation into qemuDomainPrepareHostdev()

When preparing a SCSI <hostdev/> with passthrough of a host SCSI adapter (i.e. no protocol), a virStorageSource structure is initialized and stored inside virDomainHostdevDef. But the source structure is filled in many places, with almost the same code. Firstly, qemuProcessPrepareHostHostdev() and qemuConnectDomainXMLToNativePrepareHostHostdev() are the same. Secondly, qemuDomainPrepareHostdev() allocates the src structure, only to let qemuProcessPrepareHostHostdev() fill src->path later. Well, src->path can be filled at the same place where the src structure is allocated (qemuDomainPrepareHostdev()) which renders the other two functions needless.
