powerpc/kexec: Wait for online/possible CPUs only.
kexec_perpare_cpus_wait() iterates i through NR_CPUS to check
paca[i].kexec_state of each to make sure they have quiesced.
However now we have dynamic PACA allocation, paca[NR_CPUS] is not necessarily
valid and we overrun the array; spurious "cpu is not possible, ignoring"
errors result. This patch iterates for_each_online_cpu so stays
within the bounds of paca[] -- and every CPU is now 'possible'.
