[PATCH] fix creating zero sized bio mempools in low memory system
In the very low memory systems is in the init_bio call
scale parameter set to zero and it leads to creating
zero sized mempool.
This patch prevents pool_entries parameter become zero,
so the created pool have at least 1 entry.
Mempool with 0 entries lead to incorrect behaviour
of mempool_free. (Alloc requests are not waken up
and system stalls in mempool_alloc->ioschedule).
