[libvirt] [PATCH 15/25] utils: Rename scsi->path to scsi->sg_path

[Osier Yang]

"sg_path" is more clear to indicate what it tries to store. And
later patch will use "path" to store the path like "/dev/sda".

And also rename "virSCSIDeviceGetDevStr" to "virSCSIDeviceGetSgName",
to reflect what the function does more clear.
