fix resolver query response doc

In case on positive response, the `rctx_authority_positive()` function
is called to scan the AUTHORITY section to find NS servers and related
RR (glues) to be cached.

The doc says the function was called `rctx_authority_scan()`, but it is
called `rctx_authority_positive()`.
