Wu Fengguang b320e97240 i825xx: fix paging fault on znet_probe() 
In znet_probe(), strncmp() may access beyond 0x100000 and
trigger the below oops in kvm.  Fix it by limiting the loop
under 0x100000-8. I suspect the limit could be further decreased
to 0x100000-sizeof(struct netidblk), however no datasheet at hand..
