query: add some missing 'transfer none' gi annotations

The current documentation is controverse, while it states that the
returned value is valid only while the query is is valid, which presumes
a 'transfer none' policy. But the tooltip for the 'out' annotation
states the default is 'transfer-full'.

Add the missing 'transfer none' annotations to fix this.
