QPID-6415: Core dump in ha_tests and interlink_tests with proton 0.9 (missed)
With proton 0.9 you need call pn_connectin_free before pn_transport_free.
Missed 2 cases in the previous commit.

> ---------------------------------------------------------
>
> Key: QPID-6415
> URL: https://issues.apache.org/jira/browse/QPID-6415
> Project: Qpid
> Issue Type: Bug
> Components: C++ Client
> Affects Versions: 0.30
> Reporter: Alan Conway
> Assignee: Alan Conway
> Priority: Blocker
> Fix For: 0.32
>
> Attachments: test.sh
>
>
> The qpid-send and qpid-receive clients dump core in
> ha_tests.LongTests.test_failover_send_receive
> The python test driver process dumps core in interlink_tests
> In both cases there is a double free during connection clean-up as part of a
> reconnect. It is not clear if this is a bug in the c++ qpid messaging client
> or in proton.
