isisd: Uninstall routes only if installed
In some cases, IS-IS may attempt to remove routes that have not been
installed before. We can prevent IS-IS from doing this by aborting
`isis_zebra_route_del_route` when the ISIS_ROUTE_FLAG_ZEBRA_SYNCED flag
is unset, meaning that the route is not installed in the kernel.
