PPC KVM fixes for 4.15

Four commits here, including two that were tagged but never merged.
Three of them are for the HPT resizing code; two of those fix a
user-triggerable use-after-free in the host, and one that fixes
stale TLB entries in the guest.  The remaining commit fixes a bug
causing PR KVM guests under PowerVM to fail to start.
