powerpc/pseries: fix possible memory leak in ibmebus_bus_init()

Browse source

[ Upstream commit afda85b963 ]

If device_register() returns error in ibmebus_bus_init(), name of kobject
which is allocated in dev_set_name() called in device_add() is leaked.

As comment of device_add() says, it should call put_device() to drop
the reference count that was set in device_initialize() when it fails,
so the name can be freed in kobject_cleanup().
