From: Rafal Kozik <r...@semihalf.com>
ENA_MEM_ALLOC_NODE not need to use contiguous physical memory.
Also using memset without checking if allocation succeed can cause
segmentation fault.
To avoid both issue use rte_zmalloc_socket.
Fixes: 3d3edc265fc8 ("net/ena: make coherent memory allocation NUMA-aware")
