By removing the code below, we put all the commands for all the types of
devices (SAS/SATA) as simple-Q (requeue as the device require) and I am
not sure whether it is the intention of this change.

Subject: [PATCH v4 2/4] fusion: remove iopriority handling

The request priority is now by default coming from the ioc. It was not
clear what this code was trying to do based upon the iopriority class or
data. The driver should check that a device supports priorities and use
them according to the specificiations of ioprio.
