The connection stream will be out of order while a packet received whose size exceeds 4Mb

[Tim-Zhang]

We use 4Mb as the size limit of our ttrpc message(packet) , but we didn't discard the whole packet and just continue to process the next packet https://github.com/containerd/ttrpc-rust/blob/8968bfad4d01f886135e806692c6ecbf7679b8c4/src/sync/channel.rs#L120-L127 , and then the stream of the connection will be out of order.

Affected versions:

• [x] 0.5.x
• [ ] 0.6.x
• [ ] 0.7.x
• [x] 0.8.x / master

v0.5, v0.8 and master have already fixed. I think v0.6 and v0.7 have no users currently, if anyone needs it, don't hesitate to reopen it.
