tools lib traceevent: Fix a possibly wrong memory dereference

If set_op_prio() failed, the token will be freed at out_free,
then arg->op.op would turn out to be a dangle pointer. After
returning EVENT_ERROR from process_op(), free_arg() will be
called and then it will finally see the dangling pointer.
