scsi_tools: add support for nvp reading

There is a vendor specific command to read the NVP of the device,
including the KAS. The trick is that the data is randomly
scrambled using a so-called para_noise array of random values.
There seems to be a problem when retrieving large entries (>1000
bytes typically) which causes sg_pt do behave strangely.
