LLDD TMF callbacks may return linux or other error codes instead of TMF
codes. This may cause problems in sas_scsi_find_task() ->
.lldd_query_task(), as only TMF codes are handled there. As such, we may
not return a task_disposition type from sas_scsi_find_task(). Function
sas_eh_handle_sas_errors() only handles that type, and will only progress
error handling for those recognised types.
Return TASK_ABORT_FAILED upon exit on the assumption that the command may
still be alive and error handling should be escalated.
