mm: remove broken 'kzalloc' mempool
The kzalloc mempool zeros items when they are initially allocated, but does not rezero used items that are returned to the pool. Consequently mempool_alloc()s may return non-zeroed memory. Since there are/were only two in-tree users for mempool_create_kzalloc_pool(), and 'fixing' this in a way that will re-zero used (but not new) items before first use is non-trivial, just remove it.
