#216 Ns_ConnSend() doesn't return error when NsSockSend() fails

[Dossy Shiobara]

Behavior of Ns_ConnSend() is correct in AOLserver 3.x
but was "broken" in 4.0.x and 4.1.x.

Function documentation in nsd/connio.c indicates that
Ns_ConnSend() will return -1 for error on first send,
but it ONLY returns -1 if connPtr->sockPtr == NULL. In
the case where NsSockSend() fails and returns -1, the
function returns nwrote which will equal 0.
