[PATCH] setupapi: Return CR_NO_SUCH_DEVNODE from CM_Get_Parent stub.

[Alistair Leslie-Hughes]

From: Tim Wanders <timwanders241 at gmail.com>

Fixes: https://bugs.winehq.org/show_bug.cgi?id=43831

Returning CR_SUCCESS assumes that the return value will be valid.
This causes crashes in programs which only check the return.
