Crash in [@ neqo_transport::path::Path::remote_cid]

[KershawChang]

See https://bugzilla.mozilla.org/show_bug.cgi?id=1874582
Apparently, remote_cid can be None when sending a ClosingFrame, but it's not clear why the remote_cid is not set.

See https://bugzilla.mozilla.org/show_bug.cgi?id=1881884#c0 for a way to reproduce this against the server

@valenting Would it be sufficient to not crash and instead terminate the connection? Or is an actual fix needed?

[valenting]

That's definitely better than crashing.

@KershawChang says in https://bugzilla.mozilla.org/show_bug.cgi?id=1874582#c4 this will be fixed by https://bugzilla.mozilla.org/show_bug.cgi?id=1882863, i.e., #1697. So we may be done here?

Right! I think this is fixed.
