Amos Kong 786a9f888b KVM: set upper bounds for iobus dev to limit userspace
kvm_io_bus devices are used for ioevent, pit, pic, ioapic,
coalesced_mmio.

Currently Qemu only emulates one PCI bus, it contains 32 slots,
one slot contains 8 functions, maximum of supported PCI devices:
 1 * 32 * 8 = 256. One virtio-blk takes one iobus device,
one virtio-net(vhost=on) takes two iobus devices.
The maximum of coalesced mmio zone is 100, each zone
has an iobus devices. So 300 io_bus devices are not enough.

Set an upper bounds for kvm_io_range to limit userspace.
1000 is a very large limit and not bloat the typical user.
