mod_smacks: Fix timer lifetimes to follow session instead of module module:add_timer() creates a timer that stops working after the module is reloaded or unloaded, in order to prevent leaks. However, when the timers control vital session behavior, breakage occurs after reload. E.g. sessions would stop requesting acks and stop responding to acks.
