tracing: Remove second parameter to __assign_rel_str()

Browse Source 
The second parameter of __assign_rel_str() is no longer used. It can be removed.

Note, the only real users of rel_string is user events. This code is just
in the sample code for testing purposes.

This makes __assign_rel_str() different than __assign_str() but that's
fine. __assign_str() is used over 700 places and has a larger impact. That
change will come later.
