postgres_fdw: misplaced? comments in connection.c

Hi,

The comments for pgfdw_get_cleanup_result() say this:

* It's not a huge problem if we throw an ERROR here, but if we get into error
* recursion trouble, we'll end up slamming the connection shut, which will
* necessitate failing the entire toplevel transaction even if subtransactions
* were used. Try to use WARNING where we can.

But we don’t use WARNING anywhere in that function. The right place
for this is pgfdw_exec_cleanup_query()?
