[PATCH 05/11] aacraid: use midlayer helper to terminate outstanding commands

[Hannes Reinecke <hare@suse.de>]

Use scsi_host_flush_commands() to terminate all outstanding commands
instead, and change the command result for terminated commands to
the more common 'DID_RESET' instead of 'QUEUE_FULL'.
