This patch unsets ls_remove_len and ls_remove_name if a message allocation of a remove messages fails. In this case we never send a remove message out but set the per ls ls_remove_len ls_remove_name variable for a pending remove. Unset those variable should indicate possible waiters in wait_pending_remove() that no pending remove is going on at this moment.
