ARM: CPU hotplug: fix reporting of spurious wakeups
The original scheme for reporting spurious wakeups was broken - it tried to use printk() from a context which wasn't coherent with the other CPUs, which risks corrupting the printk() data. Fix this by noting the number spurious wakeups, and only report them when we are properly woken - when we will be coherent with the rest of the system.
