[PATCH] rust_binder: clean Clippy `mem-replace-with-default` warning

[Miguel Ojeda <ojeda@kernel.org>]

Starting with Rust 1.87.0, Clippy reports:

      CLIPPY     drivers/android/binder/rust_binder_main.o
    error: replacing a value of type `T` with `T::default()` is better expressed using `core::mem::take`
       --> drivers/android/binder/node.rs:690:32
        |
    690 |             _unused_capacity = mem::replace(&mut inner.freeze_list, KVVec::new());
        |                                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: consider using: `core::mem::take(&mut inner.freeze_list)`
        |
        = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#mem_replace_with_default
        = note: `-D clippy::mem-replace-with-default` implied by `-D warnings`
        = help: to override `-D warnings` add `#[allow(clippy::mem_replace_with_default)]`

Thus clean it up as suggested.
