Initialize the dynamically-allocated transport context.
If not done, the pxNotifyThreadCtx field happens to be invalid (depending on past heap usage).
For instance it can result in a hardfault (jumping to address 0xffffffff) in the MQTT_Connect_LWT test case if the MQTT test group is run after the transport test group.
