From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

Use rte_malloc_virt2iova() to obtain the IO address of a
virtual address obtained through rte_malloc().

Fixed to use the iova address returned by rte_memzone_reserve_aligned()
as the call always returns with populating "mz->iova" with
rte_malloc_virt2iova(mz->addr).

Removed redundant rte_mem_lock_page() call to lock the pages.

Fixes: 96b0931d51e7 ("fix extended port counter statistics")
Cc: stable@dpdk.org
