* Add IDE_TFLAG_FS taskfile flag and set it for REQ_TYPE_FS requests.
* Convert ->{in,out}put_data methods to take command instead of request
as an argument. Then convert pre_task_out_intr(), task_end_request(),
task_error(), task_in_unexpected(), ide_pio_sector(), ide_pio_multi()
and ide_pio_datablock() in similar way.
* Rename task_end_request() to ide_finish_cmd().

Use blk_fs_request() in ide-taskfile.c instead of checking for:
- rq->bio in ide_pio_datablock() and task_error()
- rq->cmd_type == REQ_TYPE_ATA_TASKFILE in task_end_request()

* ide*_end_request() is only called with uptodate == 0 or uptodate == 1
so cleanup it accordingly.
* Inline ide*_end_request() content at call sites so the only user left
is ->end_request method.
* ->end_request is now used only for private driver requests so remove
handling of other requests from ide*_end_request().
