Jon TURNEY 28eb61fc04 Avoid a null dereference if IFF_BROADCAST is set but there is no broadcast address
It seems that the getifaddrs() function can return interfaces with
IFF_BROADCAST & IFF_UP set, but no broadcast address (at least
under Cygwin 1.7, this seems to happen for v6 mapped v4 addresses)

Avoid a null dereference if this ever happens
