block: mark bdrv_open_child_common() and its callers GRAPH_UNLOCKED

Browse Source 
The function bdrv_open_child_common() calls
bdrv_graph_wrlock_drained(), which must be called with the graph
unlocked. Mark it and its two callers bdrv_open_file_child() and
bdrv_open_child() as GRAPH_UNLOCKED. This requires temporarily
unlocking in vmdk_parse_extents() and making the locked section
shorter in vmdk_open().
