tools/virtio: initialize spinlocks in vring_test.c
[ Upstream commit c262f75cb6bb5a63828e72ce3b8fe808e5029479 ]
The virtio_device vqs_list spinlocks must be initialized before use to
prevent functions that manipulate the device virtualqueues, such as
vring_new_virtqueue(), from blocking indefinitely.
