Stefan Eissing 2d4efbb9b3 multi: update timer unconditionally in multi_remove_handle
When removing an easy handle from a multi, there was an optimization
to update the timer only when the removed handle had any timers.

With the introduction of the "dirty" bitset, easy handles can now cause
a timeout of 0 to be set without having anything in their timer list.
Removing such a handle needs to update the timer now always, so that
it may get cleared when there is nothing more to wait for.

The previous "not clearing a 0 timer" should not have any effect on
application's logic. Without clearing, the timer will fire and then
adjust itself to the proper value. But it would cause one more timer
fire than necessary.
