Several small fixes that clean up some cpuhp inconsistencies. The first prevents target_store() from calling cpu_down() when target == state which prevents the cpu being incorrectly marked as dying. The second just makes the boot cpu have a valid cpuhp target rather than 0 (CPU_OFFLINE) while being in state CPU_ONLINE.
A further issue which these two patches don't address is that the cpuX/online file looks at the device->offline state and can thus get out of sync with the actual cpuhp state if the cpuhp target is used to change state.
Cheers, Phil
