There exists a series of events where a kernel route is learned first( that happens to be exactly what a connected route should be ) and FRR ends up with both a kernel route and a connected route, leaving us in a very strange spot. This code change just mirrors the existing code of if there is a connected route drop the kernel route. Here we just do the reverse, if we have a kernel route already and a connected should be created, remove the kernel and keep the connected.
