We don't need to make any assumptions about the graph layout above the top node of the commit operation any more. Remove the use of bdrv_find_overlay() and related variables from the commit job code. bdrv_drop_intermediate() doesn't use the 'active' parameter any more, so we can just drop it. The overlay node was previously added to the block job to get a BLK_PERM_GRAPH_MOD. We really need to respect those permissions in bdrv_drop_intermediate() now, but as long as we haven't figured out yet how BLK_PERM_GRAPH_MOD is actually supposed to work, just leave a TODO comment there. With this change, it is now possible to perform another block job on an overlay node without conflicts. qemu-iotests 030 is changed accordingly.
