Remove unnecessary release from Arc::try_unwrap
The thread that recovers the unique access to Arc inner value (e.g., drop when ref-count strong reaches zero, successful try_unwrap), ensures that other operations on Arc inner value happened before by synchronizing with release operations performed when decrementing the reference counter. When try_unwrap succeeds, the current thread recovers the unique access to Arc inner value, so release is unnecessary.
