Really zero the zero page
While switching abd_zero_buf allocation KPI I've missed the fact
that kmem_zalloc() zeroed the allocation, while kmem_cache_alloc()
does not.  Add explicit bzero() after it.

I don't think it should have caused real problems, but leaking one
memory page content all over the pool is not good.
