tracing: Cleanup event_enable_trigger_parse() by using __free()

The enable_data variable gets freed on most error paths in
event_enable_trigger_parse(). Use free() to free it and just before
returning normally, call retain_and_null_ptr(enable_data) just before a
successful exit to keep it from being freed. On success, the enable_data
is assigned to the trigger_data->private_data field.

Also add a comment to why event_trigger_free(trigger_data) is being called
before a successful exit.
