perf machine: Mark removed threads as such

We use:

  BUG_ON(!RB_EMPTY_NODE(&thread->rb_node));

in the thread destructor as a debugging check to find out about
possibly still referenced thread instances being deleted, to do that
we need to make sure we use RB_CLEAR_NODE() right after rb_erase(),
i.e. that we use the newly introduced rb_erase_init(), that works
just like list_del_init().
