event_enable_disable() is a static method used internally by the
tracefs_event_enable/disable() API. The returned value do not obey
the description given in the documentation. Note that "ret" must
be set to -1 right before the beginning of the loop.
Fixes: fc94d1a (libtracefs: Add tracefs_event_enable/disable() API)
