In train_one we specify max_iter of dual solvers to be 300, but

the default max_iter in function definition was 500.
For example,

static int solve_l2r_l1l2_svc(const problem *prob, const parameter *param, double *w, double Cp, double Cn, int max_iter=500)

Now 500 is changed to 300 to reflect what we really used.
