rust: Drop box ptr

rwmjones · rwmjones · commit a93f06c6872f · 2022-10-14T17:44:10.000+01:00
Because of this recent change to rust, our close function warned that we calculate Box::from_raw but never use it. I added the suggested call to drop() around the function. rust-lang/rust#99270 (cherry picked from commit 6836e4c)
