Change Details

``` Although we currently don't do this, it should be possible to create a CConnman or PeerLogicValidation without a Banman instance. Therefore always check that banman exists before dereferencing the pointer. Also add comments to the m_banman members of CConnman and PeerLogicValidation to document that these may be nullptr. ``` Backport of core PR19514. Depends on D8794.
