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.
