[Patch] fad-win32.c

[Gisle Vanem <gvanem () broadpark no>]

This is a similar patch to the change of pcap-dos.c:
 https://github.com/mcr/libpcap/commit/73b5f0387199fbaa75130837b931faf770471640

I.e. the '_interfaces' suffix got lost in some other change to the puplic API.
(I don't know when). Since 'pcap_findalldevs()' is now a more generic version in 
pcap.c, the platform-specific function is called 'pcap_findalldevs_interfaces()' in 
fad-win32.c:

       if (!PacketGetAdapterNames(NULL, &NameLength))

-----

'NameLength = 0' is just in case 'PacketGetAdapterNames()' fails
w/o setting '*NameLength == 0'. It really could do that; ref. Packet32.c 
in WinPcap.
