Ensure chan->fdno always gets reset to -1 after handling a channel fd event.

Browse Source 
Since setting fdno to -1 had to be moved, a couple of other code paths that
do process an fd event return early and do not pass through the code path
where it was moved to.  So, set it to -1 in a few other places, too.
