Subject: [PATCH 0/2] Honor VPD check in usb/storage for SanDisk device

Before this patch, USB storage devices disabled VPD check by always setting
skip_vpd_check.

The first patch add a new entry to scsi_static_device_list related to SanDisk
Cruzer Blade, which have VPD, adding BLIST_TRY_VPD_PAGES flag, which implies
try_vpd_pages.

The second patch check try_vpd_pages, and only set skip_vpd_pages if
try_vpd_pages is not set.

This patches along the wwid one [1], makes SanDisk Cruzer Blade device to
present correctly wwid, vpd_pg80 and vpd_pg83 in sysfs, and let the window open
to support another USB storage devices to support and present VPD.
