Fix clippy

[Eliah Kagan (EliahKagan)]

clippy has recently begun to fail with:

error: unnecessary semicolon
  --> gix-transport/src/client/blocking_io/http/traits.rs:30:18
   |
30 |                 };
   |                  ^ help: remove
   |
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#unnecessary_semicolon
   = note: `-D clippy::unnecessary-semicolon` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(clippy::unnecessary_semicolon)]`

While it looks like this might first have been observed in #1917, it is unrelated to any change there. It happens when the current tip of main (4660f7a) is rerun, as observed in:

This is initially empty as I'm double checking that it does happen. I'll amend with a fix shortly.

Edit: Yes, it reproduces here. I've amended to add the fix.

Thank you. Please feel free to merge this when it's ready.

There's at least one other failure, which clippy didn't get to after the first one. I'll fix it too, and any others.

Edit: Running just clippy-fix and etc/copy-packetline.sh fixed it the rest of the way.
