memory: Split zones when do coalesced_io_del()
It is a workaround of current KVM's KVM_UNREGISTER_COALESCED_MMIO
interface. The kernel interface only allows to unregister an mmio
device with exactly the zone size when registered, or any smaller zone
that is included in the device mmio zone. It does not support the
userspace to specify a very large zone to remove all the small mmio
devices within the zone covered.
Logically speaking it would be nicer to fix this from KVM side, though
in all cases we still need to coop with old kernels so let's do this.
