[PATCH] zorro: Fix reading of proc/bus/zorro/* in small chunks

proc_bus_zorro_read() didn't take into account the current file position,
hence it always read from the start of the ConfigDev.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
