Your upgrade is done, but for the record, installing the HWE kernel doesn't remove the old kernel. So you still have the option to go back to that in the GRUB menu.

Also, once you're sure the HWE kernel is working, you'll probably want to remove the linux-image-generic package so you're not continuously upgrading two sets of kernels.
