[SCSI] sas_ata: Implement sas_task_abort for ATA devices
ATA devices need special handling for sas_task_abort. If the ATA command came from SCSI, then we merely need to tell SCSI to abort the scsi_cmnd. However, internal commands require a bit more work--we need to fill the qc with the appropriate error status and complete the command, and eventually post_internal will issue the actual ABORT TASK.
