Per the comment in the change - it's not always prudent to immediately
remove the rport upon first notice of a disconnect. Make all rports
wait dev_loss_tmo before being deleted (and each could have a separate
dev_loss_tmo value).

The original post was:
http://marc.info/?l=linux-scsi&m=117392196006703&w=2

The repost contains the following changes:
 - Bug fix in fc_starget_delete(). Dev_loss_tmo_callbk() was called prior to
   tearing down the target. The callback is to be the last thing called, as
   it tells the LLDD that the rport is completely finished and can be torn
   down.  Rework so that terminate_rport_io() is called to terminate the
   outstanding io. Isolated work so it's is simply "starget" work.
 - Fix holes in original patch. There were code paths that did not expect
   the dev_loss_tmo timer to be running for the non-fcp rports.
 - Bug Fix: the transport wasn't protecting against a LLDD calling
   fc_remote_port_delete() back-to-back. Thus, the dev_loss_tmo timer
   could be restarted such that it fires after the rport had been deleted.
   Validate rport state before starting the timer.

On newer levels of microcode for ipr RAID adapters supporting

Use the sysfs configurable timeout when issuing a START_UNIT
command from the scsi error handler. This is needed for devices which
take longer than thirty seconds to respond to the start
unit. The problem was observed when sending a start unit
to a disk array device in an ipr RAID adapter, which results
in the adapter firmware sending potentially multiple commands
to physical devices as a result of this command, which ended
up timing out sometimes. This patch does not change the default
value used for this command.
