Subject: [PATCH] net/vhost: initialise device as inactive

[ upstream commit aee6c97f006cea7b1c791b21b222442437ee5403 ]

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.

Fixes: ee584e9710b9 ("vhost: add driver on top of the library")
