[PATCH 03/11] dpt_i2o: use scsi_host_flush_commands() to abort outstanding commands

[Hannes Reinecke <hare@xxxxxxx>]

Rather than traversing all outstanding commands manually use the
scsi_host_flush_commands() helper to terminate all commands during
reset.
With that we can drop the cmd_list usage from the midlayer.
