gvFreeLayout: correct comments about reset and root graph

This comment was added in 44b02b91bd156cb832894fb4948bf4bc75ab27cb,
but this commit changed the cleanup to work on the given graph
(possibly a subgraph), not the root graph. The resets mentioned were
removed in 67acd9e27a053a5b80b3d1458f512d472debb434,
b3b7e0d1aea43baa81bf06a27d38447d6958c1b8 and
a71555a4ac650bf91396c77c277697b45eee44e6, although the called
`graph_cleanup` function does its own reset.
