Optimize spl_kmem_cache_free()

Because only virtual slabs may have emergency objects and these
objects are guaranteed to have physical addresses.  It can be
easily determined if the passed object is a virtual slab object
or an emergency object.  This allows us to completely optimize
the emergency object free case out of the common free path.
