WIP: OPAL disks - allow to pass through command on USB mass storage.

USB mass storage device usually do not support SECURITY IN/OUT
SCSI commands, but can support ATA12 pass-thru command
(that is used by sedutils).

This patch
 - enables SCSI security flag for USB mass storage device by default
   (NOTE: we will need a quirk to disable it as some devices are buggy)

 - USB mass storage also disables SCSI command enumeration, so test
   for SECURITY IN/OUT in SCSI layer must fail.

 - adds optional wrapper to SCSI layer for ATA12 command as an alternative
   to SECURITY IN/OUT. This wrapper is used when detection of SECURITY IN
   support fails.

With changes above the TCG OPAL support works over most USB adapters.

Note that it uncovers many other bugs that need to be debugged more.
