block: fix bdrv_replace_node_common
inore_children thing doesn't help to track all propagated permissions
of children we want to ignore. The simplest way to correctly update
permissions is update graph first and then do permission update. In
this case we just referesh permissions for the whole subgraph (in
topological-sort defined order) and everything is correctly calculated
automatically without any ignore_children.
So, refactor bdrv_replace_node_common to first do graph update and then
refresh the permissions.
Test test_parallel_exclusive_write() now pass, so move it out of
debugging "if".
