Rollup merge of #146089 - npmccallum:rustfmt, r=fmease

fix a constness ordering bug in rustfmt

Normally, changes to rustfmt go into the separate repo. But, in this case, the bug is introduced in a local change and therefore isn't present in the rustfmt repo.

Related to: #146071
Fixes rust-lang/rustfmt#6619.
