block: Mark bdrv_replace_node_common() GRAPH_WRLOCK
Instead of taking the writer lock internally, require callers to already
hold it when calling bdrv_replace_node_common(). Basically everthing in
the function needs the lock and its callers may already want to hold the
graph lock and so wouldn't be able to call functions that take it
internally.
