ZSH completions don't work

Problem
ZSH completions for Cargo provided by rustup don't work. Completions for rustup work fine though.

Looks to me (as a windows based lifeform) like they have had some work done recently, see #7296. Can you reproduce on a recent nightly toolchain?

Oh, I should have cc'd here, I left a comment on the rustup issue. I think it is due to the way rustup generates the completion, and isn't affected by the recent updates.

@ehuss I just checked your response on the rustup issue, and indeed, it works the way you did it. So it's clearly not a Cargo issue.

_cargo and _rustup completions stopped working for me while others were okay. Since zsh completions create a .zcompdump cache file, removing .zcompdump and allowing it to be regenerated got completions working again.
