This patch was originally part of a patch posted March 13, 2008.
I'm breaking this out into a separate patch as it's only somewhat related.
Applies cleanly against Sathya's latest patch and will apply correctly
(offset +29) to 2.6.26-rc3-git3.

Change mptscsih_slave_configure so it doesn't set the queue depth to 1 for SAS
protocol when sdev->id is greater than sh->max_id. The sas transport
layer assigns the target ids, incrementing with each hotplug add. With
large topologies, it doesn't take long to hit this threshold.
