getnameinfo extra len checking

[Sean Boudreau <seanb%qnx.com@localhost>]

Hi,

Does anyone know the history of this check in getnameinfo_inet()?  Is it
needed?  This breaks, for example 'nmblookup \*' from samba.  FreeBSD,
linux don't so this.

#ifdef BSD4_4                                                                
        if (sa->sa_len != salen)                                             
                return EAI_FAIL;                                             
#endif
