[dpdk-dev] [PATCH 08/36] mempool: remove const attribute in mempool_walk

[Olivier Matz <olivier.matz@6wind.com>]

Most functions that can be done on a mempool require a non-const mempool
pointer, except the dump and the audit. Therefore, the mempool_walk()
is more useful if the mempool pointer is not const.

This is required by next commit where the mellanox drivers use
rte_mempool_walk() to iterate the mempools, then rte_mempool_obj_iter()
to iterate the objects in each mempool.
