When the error handler successfully aborts a MCQ request, it only releases the command and does not notify the SCSI layer. This may cause another abort after 30 seconds timeout. This patch notifies the SCSI layer to requeue the request.
Below is error log [ 14.183804][ T74] ufshcd-mtk 112b0000.ufshci: ufshcd_err_handler started; HBA state eh_non_fatal; powered 1; shutting down 0; saved_err = 4; saved_uic_err = 64; force_reset = 0 [ 14.256164][ T74] ufshcd-mtk 112b0000.ufshci: ufshcd_try_to_abort_task: cmd pending in the device. tag = 19 [ 14.257511][ T74] ufshcd-mtk 112b0000.ufshci: Aborting tag 19 / CDB 0x35 succeeded [ 34.287949][ T8] ufshcd-mtk 112b0000.ufshci: ufshcd_abort: Device abort task at tag 19 [ 34.290514][ T8] ufshcd-mtk 112b0000.ufshci: ufshcd_mcq_abort: skip abort. cmd at tag 19 already completed.
