Fix potential peer_state deadlocks in `finish_force_close_channel`

`ChannelManager::finish_force_close_channel` exists to do cleanups
which must happen without the `per_peer_state` mutex held. However,
because it lacked lock assertions, several changes snuck in
recently which resulted in it running with peer-state locks held,
risking a deadlock if some HTLCs need to be failed.
