ISCSI: force use of sg for SMC and SSC devices
If the device we open is a SMC or SSC device, then force the use of sg. We dont have any medium changer or tape emulation so only passthrough via real sg or scsi-generic via iscsi would work anyway. Forcing sg also makes qemu skip trying to read from the device to guess the image format by reading from the device (find_image_format()). SMC devices do not implement READ6/10/12/16 so it is not possible to read from them (SSC have different CDBs). With this patch I can successfully manage a SMC device wiht iscsi in passthrough mode.
