[BUG] libp2p yamux bug showing up in deal-making

[jennijuju]

The current market in master may have trouble with making deals with nodes that on v1.10.0 and below - miner is observing that when deals being initiated, graphsync doesn't send any blocks.

Before the issue got fixed in go-libp2p, the immediate thing action we can takeon lotus is to downgrade just the yamux dependency (github.com/libp2p/go-libp2p-yamux v0.4.1) via a go mod replace,

This is not a market protocol incompatibility, but rather an issue with the latest go-libp2p dependencies.

Downgrading go-libp2p-yamux to github.com/libp2p/go-libp2p-yamux v0.4.0 via a go.mod replace directive fixes this. @magik6k will post a PR/patch soon to rectify the situation in master.

We will need a integration test reproducing this issue reliably so we can debug what's the regression in yamux.

@arajasek @raulk anything else we need to consider for this one or we can close it, since It’s classified as P0?
