qapi: Make QObject input visitor set *list reliably

Browse source 
qobject_input_start_struct() sets *list, except when it fails because
qobject_input_get_object() fails, i.e. the input object doesn't exist.

All the other input visitor start_struct(), start_list(),
start_alternate() always set *obj / *list.

Change qobject_input_start_struct() to match.

Backports commit 58561c27669ddf1c6d39ff8ce25837c6f2d9d92c from qemu
