virJSONValueObjectAppend: Clear pointer when taking ownership of passed value

Browse Source 
The parent object takes ownership of the inserted value once all checks
pass. Don't make the callers second-guess when that happens and modify
the function to take a double pointer so that it can be cleared once the
ownership is taken.
