SCSI: ses: fix VPD inquiry overrun

commit 671a99c8eb2f1dde08ac5538d8cd912047c61ddf upstream

There are a few kerneloops.org reports like this one:

That seem to imply we're running off the end of the VPD inquiry data
(although at 512 bytes, it should be long enough for just about
anything).  we should be using correctly sized buffers anyway, so put
those in and hope this oops goes away.
