if call xen_vbd_translate failed, the preq.dev will be not initialized.
so use blkif->vbd.pdevice instead (still better to print relative info).
additional information:
before commit 01c681d4c70d64cb72142a2823f27c4146a02e63, the value printed
here was bogus, as it was the guest provided value from req->u.rw.handle
rather than the actual device.
