Subject: gresolv: Make sure we will not receive DNS data after closing
X-Git-Tag: 1.9~10

gresolv: Make sure we will not receive DNS data after closing

We must close the channel when freeing the resolver object,
otherwise we might still receive data when the resolver has been
freed already.

Fixes BMC#25757
