[PATCH 1/2] ntdll: Use the parent device for everything when processing a storage IOCTL request on Mac OS.

[Charles Davis]

Many CD/DVD IOCTLs on Mac OS fail when invoked on a partition device. If you
inspect the I/O Kit registry, the reason is obvious: the device file for
the whole disk is provided by a class that understands CD/DVD commands
(IO{CD,DVD}MediaBSDClient), while the device file for the partition is
provided by a class that doesn't (IOMediaBSDClient). I don't know why
Apple did it this way, but that's the way they did this.
