NAN: Do not unpause publisher on fixed Follow-up message timeout

Do not unpause publisher if more than one second has passed from the
last Follow-up message TX or RX. There is no such behavior described in
the Wi-Fi Aware specification and it is possible for a service to need
more time to generate Follow-up messages. Leave it to the service itself
to force timeout, if desired, or terminate pauseState after the 60
second overall timeout.
