[PATCH 5/5] scsi_error: do not escalate failed EH command

[Hannes Reinecke <hare@suse.de>]

When a command is sent as part of the error handling there
is not point whatsoever to start EH escalation when that
command fails; we are _already_ in the error handler,
and the escalation is about to commence anyway.
So just call 'scsi_try_to_abort_cmd()' to abort outstanding
commands and let the main EH routine handle the rest.
