ide: set IDE_TFLAG_WRITE basing on data phase used in ide_taskfile_ioctl()
Also take care of fixing up incorrect TASKFILE_IN_DMA[Q] data phase when IDE_DRIVE_TASK_RAW_WRITE is requested (no need to do it for TASKFILE_NO_DATA and TASKFILE_[MULTI]_IN -- it had no chance of working previously). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
