driver-core: fix potential race condition in drivers/base/dd.c

This patch fix a potential race condition in the driver_bound() function
in the file driver/base/dd.c.

The broadcast of the BUS_NOTIFY_BOUND_DRIVER notifier should be done
after adding the new device to the driver list. Otherwise notifier
listener will fail if they use functions like usb_find_interface().

The patch is against kernel 2.6.33. Please merge it.
