Stop checking for valid handle in DevInfo.Close()
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(). Signed-off-by: Simon Rozman <simon@rozman.si>
