Subject: [PATCH] examples/vhost_scsi: fix product id string termination

[ upstream commit 681459bf9cd5778ada011e6d8d681436ec5394f0 ]

Use snprintf instead strncpy to get safe null string termination.
There was possible to get not terminated string after strncpy operation.

Coverity issue: 158631
Fixes: db75c7af19bb ("examples/vhost_scsi: introduce a new sample app")
