Fix issue reported by Coverity.
Coverity ID 124556
If the buffer is treated as a null terminated string in later operations,
a buffer overflow or over-read may occur.
In vhost_set_ifname: The string buffer may not have a null terminator if
the source string's length is equal to the buffer size
Fixes: 54292e9520e0 ("vhost: support ifname for vhost-user")
