[PATCH] rust: cpufreq: fix clippy::double_parens warning in Policy doctest

[John Hubbard]

Clippy reports:
    warning: consider removing unnecessary double parentheses
      --> rust/kernel/cpufreq.rs:410:60
       |
   410 |     pr_info!("The policy details are: {:?}\n", (policy.cpu(), policy.cur()));
       |                                                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Fix this by using separate format arguments.
