net: Add is_vhost_user flag to vhost_net struct
Introduce a boolean is_vhost_user field to the vhost_net structure. This flag is initialized during vhost_net_init based on whether the backend is vhost-user. This refactoring simplifies checks for vhost-user specific behavior, replacing direct comparisons of 'net->nc->info->type' with the new flag. It improves readability and encapsulates the backend type information directly within the vhost_net instance.
