ws2_32 test for non-overlapping, non-blocking WSARecv

A test case for non-overlapping, non-blocking WSARecv, that basically boils
down to testing error handling and the resetting of the error code. This is
needed for applications that check WSAGetLastError() even on successful
returning of WSARecv, resulting in connection termination and/or undefined
behaviour. A prominent example being Qt's
QNativeSocketEnginePrivate::nativeRead [1]. I guess Windows does reset the
error value to 0.

The testcase fails with unpatched WSARecv in the receiver thread, works with
patched version.

Probably could be merged into existing test_WSARecv(), though I'm unsure on how
that completion stuff affects things.
