KVM: PPC: Book3S HV: Fix host radix SLB optimisation with hash guests

Commit 68ad28a4cdd4 ("KVM: PPC: Book3S HV: Fix radix guest SLB side
channel") incorrectly removed the radix host instruction patch to skip
re-loading the host SLB entries when exiting from a hash
guest. Restore it.

Fixes: 68ad28a4cdd4 ("KVM: PPC: Book3S HV: Fix radix guest SLB side channel")
