This adds GRAPH_RDLOCK annotations to declare that callers of bdrv_get_parent_name() need to hold a reader lock for the graph because it accesses the parents list of a node. For some places, we know that they will hold the lock, but we don't have the GRAPH_RDLOCK annotations yet. In this case, add assume_graph_lock() with a FIXME comment. These places will be removed once everything is properly annotated.
