ide: set IDE_TFLAG_IN_* flags before queuing/executing command
Browse files Browse the repository at this point in the history 
* Add IDE_TFLAG_{HOB,TF,DEVICE} defines.

* Set IDE_TFLAG_IN_* flags in {do_rw,ide_no_data,ide_raw}_taskfile() users.

* Remove no longer needed ->tf_flags setup from ide_end_drive_cmd().

There should be no functionality changes caused by this patch.
