[PATCH] parport_pc: fix find_superio io compare code, should use equal test.

[qiaochong]

From: QiaoChong <qiaoch...@loongson.cn>

Fixes: 181bf1e815a2a("parport_pc: clean up the modified while loops using for").
The code find_superio should test superio[i].io == p->base then find out 
superio, fix it.
