BUG/MEDIUM: namespaces: don't fail if no namespace is used

Susheel Jalali reported a confusing bug in namespaces implementation.
If namespaces are enabled at build time (USE_NS=1) and *no* namespace
is used at all in the whole config file, my_socketat() returns -1 and
all socket bindings fail. This is because of a wrong condition in this
function. A possible workaround consists in creating some namespaces.
