ctx_dma_arr stores rte_iova_t entries, but the allocation size was
calculated using sizeof(rte_iova_t *) instead of sizeof(rte_iova_t).
Use the correct element size when allocating the array to match the
actual data type stored in ctx_dma_arr.
Fixes: 4371b402c7b ("net/bnxt: fix array overflow")

Maybe use rte_calloc() instead but fine as is.
