[dpdk-dev] [PATCH] ivshmem: add all memzones of mempool to metada

[Ferruh Yigit <ferruh.yigit@intel.com>]

Mempool consist of multiple memzones, at least from two of them.
ivshmem assumes mempool and elements are all in same memzone.

Updating code to add all memzones when a mempool added.

Fixes: d1d914ebbc25 ("mempool: allocate in several memory chunks by
default")
