Subject: session: Fix null pointer derefencing
X-Git-Tag: 0.78~200

session: Fix null pointer derefencing

When an emergency session sets back the EmergencyCall
property, all other session are notified. If a session
previously was not connected (online == FALSE) no
entry (services) was selected. We should not derefency
a NULL pointer in this case.

Fixes BMC#22880
