This patch series fixes reading the concurrent positioning ranges.

The first patch fixes reading this in libata, where it was reading
more data than a drive necessarily supports, resulting in a 
command abort. 

The second patch fixes the SCSI translated data to put the VPD page
length in the correct starting byte.

The third patch in sd, the fix is adding 4 instead of 3 for the header
length. Using 3 will always result in an error and was likely used
incorrectly as T10 specifications list all tables starting at byte 0,
and byte 3 is the page length, which would mean there are 4 total
bytes before the remaining data that contains the ranges and other
information.
