dm: usb: Do not reprobe usb hosts on "usb tree" command
Some usb hosts may have failed to probe on "usb start", i.e. an otg
host without an otg-host cable plugged in.
"usb tree" would cause the probe method of these hosts to get called
again, something which should only happen on "usb reset".
This commit fixes this.
