By default, TSO feature should be disabled because it requires
application's support to be functionnal as mentionned in the
documentation.

However, if "tso" devarg was not specified, the feature did
not get disabled.

This patch fixes this issue, so that TSO is disabled, even if
"tso=0" is not passed as devarg.

Fixes: e289400669d5 ("net/vhost: support TSO disabling")
