Simple refactor to stop passing around an unused parameter

There is no functional change in this patch.  However, this refactor
allows another patch [1] to make a simpler change to the code base.

This patch includes localizing the initialization of "internal_cidrs"
to a later spot in the "process_router" method.  This has the
advantage that it will be initialized under the same condition that it
will be used.

Fix 500 error  during router-update for dvr routers

This was caused because the l3 service plugin was
erroneously calling a method on self, whereas the
method is implemented by the core plugin.
