ioapic: clear remote irr bit for edge-triggered interrupts
This is to better emulate IOAPIC version 0x1X hardware. Linux kernel leveraged this "feature" to do explicit EOI since EOI register is still not introduced at that time. This will also fix the issue that level triggered interrupts failed to work when IR enabled (tested with Linux kernel version 4.5).
