[PATCH 2/6] tracing/branch-profiler: fix return value check on register_stat_tracer

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

The branch profiler incorrectly takes a zero return on register_stat_tracer
as an error. But zero means success.

[ Impact: remove annoying false warning on boot up ]
