This commit fixes a driver bug for SSP tasks that require task management
in the target after they complete in the SCU hardware. The problem was
manifested in the function "isci_task_abort_task", which tests
to see if the sas_task.lldd_task is non-NULL before allowing task
management; this bug would always NULL lldd_task in the SCU I/O completion
path even if target management was required, which would prevent
task / target manangement from happening.
Note that in the case of SATA/STP targets, error recovery is provided by
the libata error handler which is why SATA/STP device recovery worked
correctly even though SSP handling did not.

This patch consolidates the strings together. Purpose is to remove minor product strings extensions.
That way the future products with similar strings should not require change here.

It does not make sense to translate ref tags with unexpected values.
Instead we simply ignore them and let the upper layers catch the
problem. Ref tags that contain the expected value are still remapped.

This fixes an issues seen where a Fabric RSCN event was received
while the link was down, which resulted in repeated attempts to log back
into the fabric, which then failed, resulting in the ibmvfc driver
taking the host offline. Fix this by delaying taking any action
regarding the fabric RSCN until the link comes back up.

If an abort request times out to the virtual fibre channel adapter,
the ibmvfc driver will kick off a reset of the adapter. This
patch ensures we wait for the both the abort request and the
request being aborted to be completed prior to exiting the
eh_abort handler. This fixes a bug where the ibmvfc driver
was erroneously returning success to the eh_abort handler
then later sending back a response to the same command.

- Changes to avoid discovering NPIV port as remote port by the other
NPIV ports created on same physical port when all the NPIV ports are
part of the same zone in a fabric.
- Provided mechanism to support maximum number of target ports for a
given initiator port (physical port + NPIV ports) irrespective of the
way in which the initiator and target ports are zoned in the fabric.
- Introduced module_parameter max_rport_logins to restrict number of
remote ports discovery which includes target and initiator remote ports.

- Introduced rport qualifier structure and modified design to
export remote ports with valid pid or valid pwwn to the user space.
- Introduced old_pid field in the rport structure and made changes to
prevent re-creating a new remote port for an already existing rport
that is transitioning to a delete state. (Happens if we receive a RSCN
on the existing remote port that is getting deleted).
