tracing: Remove return values of most trace_seq_*() functions
The trace_seq_printf() and friends are used to store strings into a buffer that can be passed around from function to function. If the trace_seq buffer fills up, it will not print any more. The return values were somewhat inconsistant and using trace_seq_has_overflowed() was a better way to know if the write to the trace_seq buffer succeeded or not. Now that all users have removed reading the return value of the printf() type functions, they can safely return void and keep future users of them from reading the inconsistent values as well.
