The data returned by SetupDiGetDeviceInfoListDetail() is nil on error
which will cause the test to crash should the function fail.

The SetupDiEnumDeviceInfo() now returns a SP_DEVINFO_DATA rather than
taking it on input to fill it on return.

The former is only a subset of the later. To minimize future
maintenance, we'll provide support for extended version only.

User should not have called or deferred the Close() method should
SetupDiGetClassDevsEx() return an error (and invalid handle). And even
if user does that, a SetupDiDestroyDeviceInfoList(INVALID_HANDLE_VALUE)
is harmless. It just returns ERROR_INVALID_HANDLE - we have a unit test
for this in TestSetupDiDestroyDeviceInfoList().

Furthermore setupapi.DevInfoData has been obsoleted.
SetupDiEnumDeviceInfo() fills existing SP_DEVINFO_DATA structure now.
As other functions of SetupAPI use SP_DEVINFO_DATA, converting it to
DevInfoData and back would hurt performance.
