Subject: [PATCHv2] pm80xx: fix Adaptec 71605H hang

The IO command size is 128 bytes for these new controllers as opposed to
64 for the old 8001 controller.

The Adaptec out-of-tree driver did this correctly. After comparing the
two this turned out to be the crucial difference.

So don't hardcode the IO command size, instead use pm8001_ha->iomb_size
as that is the correct value for both old and new controllers.
