ata_qc_complete — Complete an active ATA command
| void ata_qc_complete ( | struct ata_queued_cmd * qc ); | 
Indicate to the mid and upper layers that an ATA command has completed, with either an ok or not-ok status.
   Refrain from calling this function multiple times when
   successfully completing multiple NCQ commands.
   ata_qc_complete_multiple should be used instead, which will
   properly update IRQ expect state.
