KVM: PPC: Book3S HV P9: Inject pending xive interrupts at guest entry

Browse source

If there is a pending xive interrupt, inject it at guest entry (if
MSR[EE] is enabled) rather than take another interrupt when the guest
is entered. If xive is enabled then LPCR[LPES] is set so this behaviour
should be expected.
