libata: drop @finish_qc from ata_qc_complete_multiple()
ata_qc_complete_multiple() took @finish_qc and called it on every qc before completing it. This was to give opportunity to update TF cache before ata_qc_complete() tries to fill result_tf. Now that result TF is a separate operation, this is no longer necessary. Update sata_sil24, which was the only user of this mechanism, such that it implements its own ops->qc_fill_rtf() and drop @finish_qc from ata_qc_complete_multiple().
