dispatcher: move return-early checks in "10-ifcfg-rh-routes.sh" first

A shell script is executed line-by-line. Note that for most dispatcher
events, "10-ifcfg-rh-routes.sh" has nothing to do and will just quit.
Move those checks earlier, to avoid bash executing the code that won't
be needed most of the time.
