x86/hpet: Simplify CPU online code

The indirection via work scheduled on the upcoming CPU was necessary with the
old hotplug code because the online callback was invoked on the control CPU
not on the upcoming CPU. The rework of the CPU hotplug core guarantees that
the online callbacks are invoked on the upcoming CPU.

Remove the now pointless work redirection.
