rfnoc: Resolves streamer/link segfaults on python
This commit resolves a segfault that occurs during teardown. Since
teardown isn't detereministic in python, there were cases where the
graph would destruct before the streamers or links got chance to
cleanup. This would result in a segfault. This change gives the lambda
a shared pointer to the object the callback method is calling on, so
that it won't destruct before being called.
