VMKernelAddressSpace: Disable the object depot for the RangesObjectCache.

We allocate/free ranges with the write lock held, so the depot is
just a waste, and actually in low-memory conditions hurts (if we
need a Range and there's none in the cache but there were in the
depots, a scenario I saw when trying to boot with a DEBUG=1 kernel
on my laptop.)
