radix tree test suite: fix allocation calculation in kmem_cache_alloc_bulk()

Browse Source 
The bulk allocation is iterating through an array and storing enough
memory for the entire bulk allocation instead of a single array entry. 
Only allocate an array element of the size set in the kmem_cache.
