Subject[166/251] Dont attempt to send extended INQUIRY command if skip_vpd_pages is set
3.6.11.9-rc1 stable review patch.
If anyone has any objections, please let me know.

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

From: "Martin K. Petersen" <martin.petersen@oracle.com>

[ Upstream commit 7562523e84ddc742fe1f9db8bd76b01acca89f6b ]

If a device has the skip_vpd_pages flag set we should simply fail the
scsi_get_vpd_page() call.
