This does for PR KVM what c9438092 ("KVM: PPC: Book3S HV: Take SRCU read lock around kvm_read_guest() call") did for HV KVM, that is, eliminate a "suspicious rcu_dereference_check() usage!" warning by taking the SRCU lock around the call to kvmppc_rtas_hcall(). It also fixes a return of RESUME_HOST to return EMULATE_FAIL instead, since kvmppc_h_pr() is supposed to return EMULATE_* values.
