server: dynamic neighbor deletion panic
https://github.com/osrg/gobgp/commit/318a91e31b8baed86bb66a3767525da68ae49a5d The above commit added a bug to close a closed channel; after deleting a dynamic neighbor, handleFSMMessage() must return. Otherwise cleanInfiniteChannel() is called twice. https://travis-ci.org/osrg/gobgp/jobs/483896487 Signed-off-by: FUJITA Tomonori <fujita.tomonori@gmail.com>
