usb: storage: call device_probe() after scanning
Every time a usb bus/port is scanned and a new device is detected,
we want to call device_probe() as it will give us a chance to run
additional post-processings for some purposes.
In particular, support for creating partitions on a device will be added.

Reverting this commit fixes the issue.
Note that USB drive is TOSHIBA MQ04UBD200 and it's not used for booting.
Also note that without this change 0 storage devices are detected even
when drive is attached.
