ata: libata-scsi: Return aborted command when missing sense and result TF

commit d2be9ea9a75550a35c5127a6c2633658bc38c76b upstream.

ata_gen_ata_sense() is always called for a failed qc missing sense data
so that a sense key, code and code qualifier can be generated using
ata_to_sense_error() from the qc status and error fields of its result
task file. However, if the qc does not have its result task file filled,
ata_gen_ata_sense() returns early without setting a sense key.

Improve this by defaulting to returning ABORTED COMMAND without any
additional sense code, since we do not know the reason for the failure.
The same fix is also applied in ata_gen_passthru_sense() with the
additional check that the qc failed (qc->err_mask is set).
