uhub(4): Trigger bus exploration after rescanning children.
Otherwise, if uhub4 is attached at uhub1, then when we do
# drvctl -d uhub4
# drvctl -r -a usbdevif uhub1
the rescan never discovers devices attached recursively at uhub4, and
uhub4 leaks a config_pending_incr count so it can't be detached.
