3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Martin K. Petersen" <martin.peter...@oracle.com>
commit 7562523e84ddc742fe1f9db8bd76b01acca89f6b upstream.
If a device has the skip_vpd_pages flag set we should simply fail the
scsi_get_vpd_page() call.
