Nicholas Piggin c0af639c1a KVM: PPC: Book3S HV Nested: Fix nested HFSCR being clobbered with multiple vCPUs 
commit 22f7ff0dea9491e90b6fe808ed40c30bd791e5c2 upstream.

The L0 is storing HFSCR requested by the L1 for the L2 in struct
kvm_nested_guest when the L1 requests a vCPU enter L2. kvm_nested_guest
is not a per-vCPU structure. Hilarity ensues.

Fix it by moving the nested hfscr into the vCPU structure together with
the other per-vCPU nested fields.

Fixes: 8b210a880b35 ("KVM: PPC: Book3S HV Nested: Make nested HFSCR state accessible")
