Modified Files:
        src/sys/dev/usb: uhub.c

Log Message:
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.
