The general idea is to hide spdk_vhost_dev_find declaration, so that

rte_vhost: received SET_VRING_BASE message,
calling destroy_device() as usual
user: end-user asks to remove the device (together with socket file),
OK, device is not *in use* - that's NOT the behavior we want

Instead of changing new_device/destroy_device callbacks and breaking
