Nicholas Piggin 758380b815 powerpc/64s/radix: Fix radix_kvm_prefetch_workaround paca access of not possible CPU 
If possible CPUs are limited (e.g., by kexec), then the kvm prefetch
workaround function can access the paca pointer for a !possible CPU.

Fixes: d2e60075a3 ("powerpc/64: Use array of paca pointers and allocate pacas individually")
