[dpdk-dev] [PATCH] net/vhost: Initialise vid to -1

[Ciara Loftus]

rte_eth_vhost_get_vid_from_port_id returns a value of 0 if called before
the first call to the new_device callback. A vid value >=0 suggests the
device is active which is not the case in this instance. Initialise vid
to a negative value to prevent this.
