Markus Armbruster 9f742c28f5 qdev: Clean up qdev_connect_gpio_out_named() 
Both qdev_connect_gpio_out_named() and device_set_realized() put
objects without a parent into the "/machine/unattached/" orphanage.

qdev_connect_gpio_out_named() needs a lengthy comment to explain how
it works.  It exploits that object_property_add_child() can fail only
when we got a parent already, and ignoring that error does what we
want.  True.  If it failed due to "duplicate property", we'd be in
trouble, but that would be a programming error.

device_set_realized() is cleaner: it checks whether we need a parent,
then calls object_property_add_child(), aborting on failure.  No need
for a comment, and programming errors get caught.

Change qdev_connect_gpio_out_named() to match.
