[ofw] winOFED 3.2 RC1 - DAPL/RDMACM unable to connect.

[Smith, Stan]

getaddrinfo("..localmachine", NULL, NULL, &res); used to return the IPv4 address bound to the local IPoIB; in preference to the IPv6 address.
Today, getaddrinfo() returns the IPv6 address, default IPv6 address in some cases.
Use 'hint' struct to qualify which local IPoIB address is desired (IPv4).
