[PATCH] net/virtio-user: fix eventfd sharing in secondary process

[Samar Yadav]

Agreed Stephen, will switch to rte_calloc in patch v2:

- pp->kickfds = rte_malloc("virtio_user_proc_priv",
- total_queues * sizeof(int), 0);
- pp->callfds = rte_malloc("virtio_user_proc_priv",
- total_queues * sizeof(int), 0);
+ pp->kickfds = rte_calloc("virtio_user_proc_priv",
+ total_queues, sizeof(int), 0);
+ pp->callfds = rte_calloc("virtio_user_proc_priv",
+ total_queues, sizeof(int), 0);
