powerpc/kdump: Only save CPU state first time through the secondary CPU capture code
We might enter the secondary CPU capture code twice, eg if we have to unstick some CPUs with a system reset. In this case we don't want to overwrite the state on CPUs that had made it into the capture code OK, so use the cpus_state_saved cpumask for that and make it local to crash_ipi_callback. For controlling progress now use atomic_t cpus_in_crash to count how many CPUs have made it into the kdump code, and time_to_dump to tell everyone it's time to dump.
