ipack: split ipack_device_register() in several functions
One function is ipack_device_init(). If it fails, the caller should execute
ipack_put_device().
The second function is ipack_device_add that only adds the device. If
it fails, the caller should execute ipack_put_device().
Then the device is removed with refcount = 0, as device_register() kernel
documentation says.
ipack_device_del() is added to remove the device.
