KVM: PPC: Book3S: Take the kvm->srcu lock in kvmppc_h_logical_ci_load/store() commit 3eb4ee68254235e4f47bc0410538fcdaede39589 upstream. Access to the kvm->buses (like with the kvm_io_bus_read() and -write() functions) has to be protected via the kvm->srcu lock. The kvmppc_h_logical_ci_load() and -store() functions are missing this lock so far, so let's add it there, too. This fixes the problem that the kernel reports "suspicious RCU usage" when lock debugging is enabled.
