KVM: x86: don't notify userspace IOAPIC on edge EOI
On real hardware, edge-triggered interrupts don't set a bit in TMR, which means that IOAPIC isn't notified on EOI. Do the same here. Staying in guest/kernel mode after edge EOI is what we want for most devices. If some bugs could be nicely worked around with edge EOI notifications, we should invest in a better interface.
