Now that all of the Property arrays are counted, we can remove
the terminator object from each array. Update the assertions
in device_class_set_props to match.
With struct Property being 88 bytes, this was a rather large
form of terminator. Saves 30k from qemu-system-aarch64.

We currently don't clear the interrupts if they are disabled. This means
that if an interrupt occurs and the guest disables interrupts the QEMU
IRQ will remain high.
This doesn't immediately affect guests, but if the
guest re-enables interrupts it's possible that we will miss an
interrupt as it always remains set.
Let's update the logic to always call qemu_set_irq() even if the
interrupts are disabled to ensure we set the level low. The level will
never be high unless interrupts are enabled, so we won't generate
interrupts when we shouldn't.
