Wei Yang ceb08ee965 lib/interval_tree: fix the comment of interval_tree_span_iter_next_gap() ...

The comment of interval_tree_span_iter_next_gap() is not exact, nodes[1]
is not always !NULL.

There are threes cases here. If there is an interior hole, the statement
is correct. If there is a tailing hole or the contiguous used range span
to the end, nodes[1] is NULL.
