MFC r341833:

pf: Prevent integer overflow in PF when calculating the adaptive timeout.

Mainly states of established TCP connections would be affected resulting
in immediate state removal once the number of states is bigger than
adaptive.start.  Disabling adaptive timeouts is a workaround to avoid this bug.
Issue found and initial diff by Mathieu Blanc (mathieu.blanc at cea dot fr)
