module traceexit.c does not execute exit_code if exit.c parameter is incorrect

[jbericat]

Modify this:

 if (exit_code < 0 || exit_code > 255) { 
        printk ("Incorrect exit code --> %d WAS NEITHER EXECUTED NOR CAPTURED IN /proc/traceexit.\n", exit_code);
	return;
 } else {
	exit_codes_count[exit_code]++;
	printk ("exit code %d captured at /proc/traceexit\n", exit_code);
	return original_sys_exit(exit_code);
 }

so return original_sys_exit(exit_code); is called after the if clause (the first return call must be removed)
