ser_gigaset: fix deallocation of platform device structure
commit 4c5e354a upstream. When shutting down the device, the struct ser_cardstate must not be kfree()d immediately after the call to platform_device_unregister() since the embedded struct platform_device is still in use. Move the kfree() call to the release method instead.
