    wg: Style cleanups and minor updates to wg_noise.[ch]
    
    - Remove unnecessary assignments that are already ensured by
      kmalloc(M_ZERO).
    - Use sizeof() in bzero()/explicit_bzero() to simplify the code.
    - Improve noise_kdf() by adding KKASSERT() to check the arguments,
      by adding comments to blake2s_hmac() arguments.
    - Swap the 'arg' and 'public' parameters to look more sensible.
    - Move inline functions to the file top.
    - Rename noise_timer_expired() to timer_expired(), similar to the same
      function in 'wg_cookie.c'.
    - Change 'ENOSPC' to 'ENOMEM' for consistency.
    - Add 'static' qualifier to the MALLOC_DEFINE().
    - Fix and adjust the comments a bit.
    - Adjust code style to align with ours.
