[ 24/76] SCSI: virtio-scsi: initialize scatterlist structure

[Greg Kroah-Hartman]

3.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Richard W.M. Jones" <rjones@xxxxxxxxxx>

commit 2e9c9dfde00a6466441e93033cf2c37f720bdacf upstream.

The sg struct is used without being initialized, which breaks
when CONFIG_DEBUG_SG is enabled.
