KVM: Minor memory slot optimization
If a slot is removed or moved in the guest physical address space, we first allocate and install a new slot array with the invalidated entry. The old array is then freed. We then proceed to allocate yet another slot array to install the permanent replacement. Re-use the original array when this occurs and avoid the extra kfree/kmalloc.
