stream: Traverse graph after modification
bdrv_cor_filter_drop() modifies the block graph. That means that other
parties can also modify the block graph before it returns. Therefore,
we cannot assume that the result of a graph traversal we did before
remains valid afterwards.
We should thus fetch `base` and `unfiltered_base` afterwards instead of
before.
