The code of cobalt_print_sched_params is carried into the format string
in tracefs, and trace-cmd tries to make any sense out of it. While it
can process simply statements, this code is too complex and will prevent
the parsing.

Convert it into a function. That still does not resolve the parsing
issue of trace-cmd, but that can be addressed by a custom plugin which
can then interpret this tracepoint. That wouldn't be possible with the
broken format string.
