[SCSI] transport_class: BUG if we can't release the attribute container
Every current transport class calls transport_container_release but
ignores the return value. This is catastrophic if it returns an error
because the containers are part of a global list and the next action of
almost every transport class is to free the memory used by the
container.
Fix this by making transport_container_release a void, but making it BUG
if attribute_container_release returns an error ... this catches the
root cause of a system panic much earlier. If we don't do this, we get
an eventual BUG when the attribute container list notices the corruption
caused by the freed memory it's still referencing.
Also made attribute_container_release __must_check as a reminder.

[SCSI] fix barrier failure issue
Currently, if the barrier command fails, the error return isn't seen
by the block layer and it proceeds on regardless. The problem is that
SCSI always returns no error for REQ_TYPE_BLOCK_PC ... it expects the
submitter to pick the errors out of req->errors, which the block
barrier functions don't do.
Since it appears that the way SG_IO and scsi_execute_request() work
they discard the block error return and always use req->errors, the
best fix for this is to have the SCSI layer return an error to block
if one actually occurred (this also allows us to filter out spurious
errors, like deferred sense).
This patch is a bug fix that will need backporting to stable, but it's
also quite a big change and in need of testing, so we'll incubate in
the main kernel tree and backport at the -rc2 or so stage if no
problems turn up.

[SCSI] mptsas: do not use ioc->handle to locate hba portinfo structure
While performing hardware raid reset testing via the raid's client, I
noticed that sometimes, following the reset, that there would be more
raid targets in the lsscsi output than there actually were raid
targets. I tracked this down to the following issue.
Fusion cannot always find the mptsas_portinfo structure for the hba
because it uses the handle stored in ioc->handle to locate it. The
problem is that the firmware can change the handle associated with the
hba when h/w raid is reset (via the raid client). When this happens,
the driver will allocate another mptsas_portinfo structure and link it
into the chain of said structures. This ultimately causes confusion
within the driver resulting in targets not being removed when they
should be.
Eric Moore pointed out that the hba's portinfo structure is always the
first structure on the sas_topology list. This patch modifies
mptsas.c to access the hba's portinfo structure by taking the first
structure on said list.
