libata: fix translation of concurrent positioning ranges
commit 6d11acd452fd885ef6ace184c9c70bc863a8c72f upstream.
Fixing the page length in the SCSI translation for the concurrent
positioning ranges VPD page. It was writing starting in offset 3
rather than offset 2 where the MSB is supposed to start for
the VPD page length.
