[PATCH] event-loop: remove dead code

[David Herrmann]

There is really no need to increment "n" if we never read the value. The
do-while() loop overwrites the value before it is read the first time.

I am not sure what the intention is here. Either we want a normal "while()" loop
below and only do the post-dispatch if the real dispatch returned >0. Or, this
is just dead code and we can remove it.
I assumed the latter is true so this patch simply removes what has no effect.
