[PATCH 31/35] ips: use correct command completion on error

[Hannes Reinecke <hare@suse.de>]

A non-zero queuecommand() return code means 'busy', ie the command
hasn't been submitted. So any command which should be failed need
to be completed via the ->scsi_done() callback with the appropriate
result code set.
