Dangling wantlists

We have a small cluster with approximately 30 machines, we notice bitswap stat reports non-zero wantlist length even though there is no task running. Something like this
```
Bitswap Stat
WantlistLength: 31
Peers:
BlocksReceived: 8178

```

After running ipfs log to investigate, seems like there's a race condition between `CANCEL_WANT_BLOCK` & `WANT_HAVE` after receiving valid block from any peer. Here's a relevant log for cid `bafkreig4xh7u5iveim7sxhbngvr4daggxxtsdatl5wejk4rea6saeyx5ke`

```

Notice how bitswap still send `WANT_HAVE` to one of the peers even though it already has a valid response.

From what I understand, there might be two goroutines running receive message loop and send loop, a race condition might happen in the following scenario:
1. sendloop is looping through all of the session's peers to send `WANT_HAVE`
2. receiveloop received a valid block, it loop through all session's peers, check if peer has already sent `WANT_HAVE` to send `CANCEL_WANT_BLOCK`, let's say an arbitrary peer P is in a state of hasn't send `WANT_HAVE`, so it'll be ignored.
3. sendloop is currently looping peer P, it notice that it hasn't send `WANT_HAVE` to this peer so it'll send a request and record it in peermanager
4. receiveloop exit, session will cleanup all resources & existing wantlist, when peer manager receive `HAVE` response from peer P, it cannot find interested session to process this event, thus this cid's wantlist will never be cleanup

I can help with code if anybody is kind enough to provide insight into the loop mechanism in ipfs.
