ide-disk: use do_rw_taskfile() (take 2)
* Add IDE_TFLAG_DMA_PIO_FALLBACK taskfile flag to indicate the need
to skip loading taskfile registers in do_rw_taskfile().
* Export do_rw_taskfile().
* Convert __ide_do_rw_disk() to use do_rw_taskfile().
* Unexport ide_tf_load().
* Unexport {pre_task_out,task_in}_intr() and make it static.
* Remove incorrect comment about do_rw_taskfile() from <linux/ide.h>.
There should be no functionality changes caused by this patch.
v2:
* Add missing blk_fs_request() check to task_dma_ok() (for VDMA).
