fou: Prevent unbounded recursion in GUE error handler also with UDP-Lite
In commit 11789039da53 ("fou: Prevent unbounded recursion in GUE error
handler"), I didn't take care of the case where UDP-Lite is encapsulated
into UDP or UDP-Lite with GUE. From a syzbot report about a possibly
similar issue with GUE on IPv6, I just realised the same thing might
happen with a UDP-Lite inner payload.
Also skip exception handling for inner UDP-Lite protocol.
Fixes: 11789039da53 ("fou: Prevent unbounded recursion in GUE error handler")
