assert in inet_ntop_ez()

[Gisle Vanem <giva () bgnett no>]

The nbase/nbase_misc.c at line 153:

#if HAVE_IPV6
 else {
   assert(sin->sin_family == AF_INET6);

gets an assert on Win32 if you have an interface that is down. In my case
it's a WiFi-adapter in ad-hoc mode. IMHO it would be okay for 
inet_ntop_ez() to return NULL if 'sin->sin_family' is 0. Patch attached.

PS. The interace list of "nmap --iflist" looks like this here:
