Driver issues all non-ReadWrite IOs for TYPE_ENCLOSURE devices through
the fast path with invalid dev handle and fast path inturn directs all
the IOs to the firmware. As firmware stopped handling those IOs from
SAS3.5 generation of controllers (Ventura and its onward generations)
lead to IOs failure.

The driver will issue all the non-ReadWrite IOs for TYPE_ENCLOSURE devices
directly to firmware from SAS3.5 generation of controllers.
