[PATCH v3 05/19] sata: call device_probe() after scanning

Every time a sata 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.
