[PATCH net] ethernet: xircom: small clean up in setup_xirc2ps_cs()

The get_options() function takes the whole ARRAY_SIZE().  It doesn't
matter here because we don't use more than 7 elements.

That code looks very dubious to me.
It looks as though it expects all of the ints[] array to be initialised
to -1, not just the first element.

I'm pretty sure you're right and I thought about changing it when I sent
the patch but it doesn't matter.  It's not required to initialize that
code anyway because either get_options() will initialize it or it won't
be used.
