Revert "apic: save apic_delivered flag"

This reverts commit 07bfa354772f2de67008dc66c201b627acff0106.
The global variable is only read as part of a

            apic_reset_irq_delivered();
            qemu_irq_raise(s->irq);
            if (!apic_get_irq_delivered()) {

sequence, so the value never matters at migration time.
