[PATCH 1/4] module-tunnel: Fix for new protocol versions

[mkbosmans@xxxxxxxxx (Maarten Bosmans)]

The commit 7ebc5033 resulted in segfaults, because format->plist was not allocated.
The solution is not to allocate pa_format_info on the stack, but to properly use pa_format_info_new().
Also a typo regarding pa_tagstruct_putu8 is corrected.
