N2N topologies.
Semantic changes in ISP24xx firmware behaviour inadvertently
caused the driver to believe an F-port topology was present in an
N_port-to-N_port configuration.

[SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine.
and given:
- the process-context requirements of the FC transport
rport-APIs.
- lack of port-type RSCN processing logic for ISP24xx and newer
chips.
it's time now to remove the state-machine logic from mainline.

In qla2x00_reset_chip the driver first takes the hardware lock,
and then later on takes the mbx lock.
In the mailbox_command code.. it goes the other way around.

Fix the driver to return SUCCESS if the firmware or driver doesn't
have a command to abort, i.e., it's already been returned. Without
this patch, error recovery will take the target offline as it tries
harder and harder to get the driver to return the command it no longer
has.

If qla2x00_probe_one() fails before calling request_irq() but gets to
qla2x00_free_device() then it will mistakenly try to free an irq it didn't
request. It's chosing to free based on ha->pdev->irq which is always set.
host->irq is set after request_irq() succeeds so let's use that to decide
to free or not.
This was observed and tested when a silly set of circumstances lead to
firmware loading failing on a 2100.

after relogin.
A target can LOGO an initiator at any time (i.e. during I/O,
due to a controller hicup, or as a simple authentication
mechanism after an initial CDB command), when this occurs,
the driver attempts to relogin (PLOGI) to the device via the
DPC thread. Add code to make the appropriate upcall to the
FC transport layer (fc_remote_port_add()) upon successful
completion of the PLOGI.

The driver can typically detect port-loss during an
interrupt context (i.e. via interrogation of a status IOCB's
completion status [CS_PORT_LOGGED_OUT]. Due to the calling
requirements of the fc_rport APIs, the driver would defer
removal of the device to the default workqueue. If the
work-item was preceded by an event which caused the port to
obtain visibility (relogin successful, target re-logged into
the topology), deferred removal could inadvertently drop the
rport. The code also no longer defers removal via the
default workqueue, instead opting for use of the driver's
own DPC thread.

Given the semantic changes in both the device-model and
fc-transport APIs, the driver's handling of port-type RSCNs
via a series of ADISCs and PLOGIs can cause series of
badness ranging from unexpectedly device loss to devices not
being discovered.
In the interim, disable (via a module-parameter) this
feature and allow RSCN management to continue to occur
within the driver's DPC thread.
