save/restore cpu_weight and cpu_cap

This patch allows vcpus_params cpu_weight and cpu_cap to be saved and
restored.  Most the code to support this already existed, but the save path
needed to be updated to explicitly save these params, and the restore path
needed to be updated to resend the params down to the kernel.
