This patch properly registers the 16 byte command length capability of
the megaraid_sas controlled hardware with the scsi midlayer.  All
megaraid_sas hardware supports 16 byte CDB's.

This patch cleans up that interface by having the lld and class
pass a iscsi_cls_session or iscsi_cls_conn between each other when
the function is used by HW and SW iscsi llds. This way the lld
does not have to remember if it has to send a handle or pointer
and a handle or pointer to connection, session or host.

This also has the class verify the session handle that gets passed from
userspace instead of using the pointer passed into the kernel directly.

Received From Mark Salyzyn.

In order to support user tools accessing the array components (SMART,
Mode Page information, Cache page adjustments, WWN determination,
Firmware updates etc), we take advantage of the no_uld_attach flag and
deprecate the code that filters Inquiries to block the requests to array
components. The quirk prevents the sd layer from attaching to the
components.

We also took the opportunity to balance the queue depths based on the
total adapter queue depth to the array devices to reduce the chances of
starvation.

This patch sets up some device quirks surrounding arrays to inform the
