libtracefs: Have tracefs_tracer_set() return zero on success
The tracefs_tracer_set() does a ret = write() to write the tracer name
into the current_tracer file, but then it returns the ret as well. "write"
returns the number of bytes written, but tracefs_tracer_set() is suppose
to return 0 on success.
Have it return 0 instead of the number of bytes written on success.
