net: introduce qemu_get_nic()
To support multiqueue, this patch introduces a helper qemu_get_nic() to get NICState from a NetClientState. The following patches would refactor this helper to support multiqueue. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
