[dpdk-stable] [PATCH] net/mlx5: fix check for rte calloc return value

[Asaf Penso]

rte_calloc functions returns a non-null pointer in case of
success and null pointer in case of failure.

The return value should be checked and the function flow
should take that into consideration.

This patch adds a check for rte_calloc return value in function
flow_list_create.

Fixes: 84c406e7 ("net/mlx5: add flow translate function")
