[ofw][patch][WinVerbs tests] fix IPv6 related connection problem

[Leonid Keller]

All WinVerbs test (client part) require host IP address as a parameter.
We used to use IPv4 address as it is more comfortable.
But if IPv6 protocol is installed, which is default for Win2008, the
connection code in the tests doesn't work right.
This patch suggest a fix, that limiting the usage of host addresses to
IPv4 only.
The same limitation exists today also in tools\perftests.
