This patch fixes a regression introduced by commit d5c11bbb65
for logging NetworkEvents when lingering and unlingering a network.
Commit d5c11bbb65 removed an overloaded constructor for the
NetworkEvent class, which caused NetworkEvents with event type of
LINGER or UNLINGER logged in ConnectivityService to have incorrect
event types (set to the network id instead) and incorrect duration
(set as the event type instead).
