(drivers/net/lib8390: fix warning, trim trailing whitespace)

The problem is that ei_inb_p() is using various #defines (from
drivers/net/8390.h) that use EI_SHIFT, which in the zorro8390 case uses
ei_local.  Since zorro8390 is only build for m68k, guard the definition of
ei_local with CONFIG_M68K

The patch below fixes the zorro8390 build, and I think will keep the warnings
that Jeff is trying to silence silenced.

Thanks for chasing this down!

Technically, it could also happen on PPC (APUS), but all APUS support got
removed a few months ago.
So maybe CONFIG_ZORRO is more appropriate?

(CONFIG_ZORRO8390 || CONFIG_ZORRO8390_MODULE is probably frowned upon?)

No, he didn't.  He reran the build by hand.  Sorry, but there appears to
a bug somewhere in our build system (or one of the tools it is using)
that very occasionally loses a line of the log.  We are trying to track
it down.

I have applied this patch to today's linux-next, so that this particular
bug will not prevent the m68k builds.  I am hoping someone will pick it
up (or an equivalent patch) so I can drop it again.

Well as it turns out it can happen in a few other plcaes (the same error
is visible on sh aswell:

Below is a new fix. Thoughts?.

The problem is that ei_inb_p() is using various #defines (from

architectures use ei_local.  Tag ei_local as "__maybe_unused" to keep it
around and keep the warnings the original commit is trying to silence
