With headsets, a2dp_transport::session == NULL usually until stream resumes. During this time, delay_reporting_exists() incorrectly returns FALSE, because streams corresponding to NULL session cannot be found. As no further "Delay" property updates will usually arrive, the property remains missing even though delay reports have been received. Fix by setting a2dp->session when processing a delay report, if missing.
