The following code needs to be added to ide_end_drive_cmd(),
since ide_error() calls ide_end_drive_cmd() after ide_dump_status()
has left the registers pointing at the high order part of the LBA.
Using the taskfile ioctl will then lead to hobRegister[] and
subsequently hob_ports[] being loaded with the wrong values.
