Improve lock and unlock symmetry

- Move destruction of per-ring locks to netmap_dtor_locked to mirror the
initialization that happens in NIOCREGIF.  Otherwise unloading a netmap-
capable interface that was never put into netmap mode would try to
mtx_destroy an uninitialized mutex, and panic.

- Destroy core_lock in netmap_detach, mirroring init in netmap_attach.

- Also comment out the knlist_destroy for now as there is currently no
knlist_init.
