[PATCH v2 5/5] vhost: use strlcpy instead of strncpy

[Stephen Hemminger]

Some tools such as gcc address sanitizer will complain if strncpy
is used to completely fill a string since it will not be null
terminated. Since the previous code forced as null at end,
use strlcpy() to get the same effect.
