aacraid: IOCTL fix

After getting the platform shutdown command "VM_CloseAll" response from the
firmware, driver was getting configuration IOCTL request from the upper layers
and it sends down to firmware. This causes firmware assert issue.

This patch fixes the firmware assert issue. During the shutdown, if driver
gets commands from the upper layer, driver sends error code to the upper
layers.

[SCSI] aacraid: add an ifdef'd device delete case instead of taking the device offline

Problem description:
--------------------

The problem reported by one of the customer was when a logical array
is deleted(from the SDK, from the GUI, from arcconf) then the
corresponding physical device (/dev/sdb, for example) is not removed
from the Linux namespace. So you end up with a "dead" device
entry. And some of the linux tools go slightly wonky.

Solution:
---------

Based on the notification from FW, the driver calls
"scsi_remove_device" for the DELETED drive. This call not only informs
the scsi device status to the SCSI mid layer and also it will remove
corresponding scsi device entries from the Linux sysfs.

[SCSI] aacraid: fix File System going into read-only mode

These particular problems were reported by Cisco and SAP and customers
as well. Cisco reported on RHEL4 U6 and SAP reported on SLES9 SP4 and
SLES10 SP2. We added these fixes on RHEL4 U6 and gave a private build
to IBM and Cisco. Cisco and IBM tested it for more than 15 days and
they reported that they did not see the issue so far. Before the fix,
Cisco used to see the issue within 5 days. We generated a patch for
SLES9 SP4 and SLES10 SP2 and submitted to Novell. Novell applied the
patch and gave a test build to SAP. SAP tested and reported that the
build is working properly.

We also tested in our lab using the tools "dishogsync", which is IO
stress tool and the tool was provided by Cisco.

Issue1: File System going into read-only mode

Root cause: The driver tends to not free the memory (FIB) when the
management request exits prematurely. The accumulation of such
un-freed memory causes the driver to fail to allocate anymore memory
(FIB) and hence return 0x70000 value to the upper layer, which puts
the file system into read only mode.

Fix details: The fix makes sure to free the memory (FIB) even if the
request exits prematurely hence ensuring the driver wouldn't run out
of memory (FIBs).


Issue2: False Raid Alert occurs

When the Physical Drives and Logical drives are reported as deleted or
added, even though there is no change done on the system

Root cause: Driver IOCTLs is signaled with EINTR while waiting on
response from the lower layers. Returning "EINTR" will never initiate
internal retry.

Fix details: The issue was fixed by replacing "EINTR" with
"ERESTARTSYS" for mid-layer retries.

[SCSI] aacraid: add Voodoo Lite class of cards.

The cards being added are supported in a limited sense already through
family matching, but we needed to add some functionality to the driver
to expose selectively the physical drives. These Physical drives are
specifically marked to not be part of any array and thus are declared
JBODs (Just a Bunch Of Drives) for generic SCSI access.

We report that this is the second patch in a set of two, but merely
depends on the stand-alone functionality of the first patch which adds
in that case the ability to report a driver feature flag via sysfs. We
leverage that functionality by reporting that this driver now supports
this new JBOD feature for the controller so that the array management
applications may react accordingly and guide the user as they manage
the controller.
