The 4 gig version of the Seagate Medalist Pro seems to have the same
trouble with tagged queueing as the 6.5 gig version.
So, I've added a quirk entry for it to limit it to two outstanding
transactions at a time, just like the 6.5G version. While I'm at it, add a
quirk for the 9G version of the drive, since it most likely has the same
problem.
