Bug ID: 37667
           Summary: GetRawInputDeviceList() does not set an error code on
                    failure
           Product: Wine
           Version: 1.7.32
          Hardware: x86

When GetRawInputDeviceList() is passed a buffer which is too small, the
function should set the last error code to ERROR_INSUFFICIENT_BUFFER and return
failure (see
http://msdn.microsoft.com/en-us/library/windows/desktop/ms645598(v=vs.85).aspx).
 However, the current Wine implementation does not set the last error code,
meaning that callers expecting to see ERROR_INSUFFICIENT_BUFFER will behave
incorrectly.

Patch attached (the patch is against wine-1.7.29 but the code is unchanged in
git).
