Problem

anchor-spl with metadata feature has a compile error and a few warnings after the recent upgrade(#2632).

warning: unused variable: `name`

    = note: partial move occurs because `data.uses` has type `Option<Uses>`, which does not implement the `Copy` trait

@acheroncrypto Thanks for looking into this. I need to address these issues on the Rust client, likely I will need to publish a patch/minor version. I will create a PR on anchor once I have done the fix.
