Systems with a large number of CPU cores (192+) may trigger the large allocation warning in multilist_create() on Linux. Silence the warning by converting the allocation to vmem_alloc(). On Linux this results in a call to kvalloc() which will alloc vmem for large allocations and kmem for small allocations. On FreeBSD both vmem_alloc and kmem_alloc internally use the same allocator so there is no functional change.
