description:
Add some missing channel order related ioctl defines.

These are no-ops (unimplemented) on both FreeBSD and Solaris
and the one piece of code I've found that uses it seems to assume the
call will fail so it should be safe to leave this returning EINVAL.

However, it does need the definitions to compile...
