ide: remove 'command_type' field from ide_task_t
* Add 'data_buf' and 'nsect' variables in ide_taskfile_ioctl()
to cache data buffer pointer and number of sectors to transfer
(this allows us to have only one ide_diag_taskfile() call).
* Add IDE_TFLAG_WRITE taskfile flag and use it to check whether
the REQ_RW request flag should be set.
* Move ->command_type handling from ide_diag_taskfile() to
ide_taskfile_ioctl() and use ->req_cmd instead of ->command_type.
* Add 'nsect' parameter to ide_raw_taskfile().
* Merge ide_diag_taskfile() into ide_raw_taskfile().
* Initialize ->data_phase explicitly in idedisk_prepare_flush(),
ide_start_power_step() and ide_disk_special().
* Remove no longer needed 'command_type' field from ide_task_t.
* Add #ifndef/#endif __KERNEL__ to <linux/hdreg.h> around no
longer used by kernel IDE_DRIVE_TASK_* and TASKFILE_* defines.
There should be no functionality changes caused by this patch.
