mm, mempool: use '%zu' for printing 'size_t' variable

fix printk warning

Commit 8b65aaa9c53404 ("mm, mempool: poison elements backed by page allocator")
caused the following build warning on ARM:

mm/mempool.c:31:2: warning: format '%ld' expects argument of type 'long int', but argument 3 has type 'size_t' [-Wformat]

Use '%zu' for printing 'size_t' variable.
