wmaker: removed variable 'done' to prepare return status in 'wNETWMProcessClientMessage'

Using a variable to store the return value that will be used later is not a
good idea, because it forces to track everywhere in the function when
needing to work on the function.

This patch removes the variables and places explicit return if each case,
so on first look it is clear where the code stops.

It also fixes a bug where the function would handle an event but still
returns False (meaning the event was not treated), whose root cause was
coming from the complexity brought by the variable.
