Fix IRQ allocation for goldfish devices.
There were two issues fixed here:
1. IRQ allocation (for a device) has never been checked on going out of bounds.
2. In x86 platform some IRQs were reserved (for kbd, mouse, and exception), but IRQ allocation
for goldfish devices didn't check for those reserved IRQs being assigned to a device.
