    wg: Port #32: refactor interface code and avoid deferred free
    
    - Refactor wg_clone_destroy() to not use async/deferred free, and thus
      avoid the async call of wg_clone_deferred_free() via noise_local_free().
      As a consequence, remove the 'l_arg' and 'l_cleanup' members from
      'noise_local' struct; also remove the noise_local_arg() API.
    
    - Fix wg_clone_destroy() to not clear 'if_softc' at the beginning of the
      destruction, which fixes a panic of NULL dereference in wg_output()
      via the if_purgeaddrs_nolink() call.
    
    - Remove the 'WGF_DYING' flag and the associated obsolete code.
    
    - Remove the 'clone_count' global as it's no longer required.
