Subject: [PATCH 0/2] tracing/user_events: Fix struct arg size match check

The edge case of struct fields having an extra size argument got missed
when checking if events have the same name and arguments. This lead to
events not being able to register if a matching event name was already
created with a struct argument.

This series simply fixes this and adds a self test to ensure we do not
miss it again.
