tracing: initialize return value for __ftrace_set_clr_event
Commit 8f31bfe538ebafac187d2d4465a92e1d9ee6d8c2
tracing/events: clean up for ftrace_set_clr_event()
Moved out the code for ftrace_set_clr_event into a helper funciton but
did not initialize the return value. As a result, we do not warn about
a typo in the echoing of events in set_event.
This patch restores the old warning:
# echo foobar > set_event
-bash: echo: write error: Invalid argument
[ Impact: restore warning of invalid entries to set_event ]
