[TRIVIAL PATCH V2] smsc9194: Remove uncompilable #if 0'd use of pr_dbg

[Joe Perches]

No pr_dbg method exists.

While this code is #if 0'd, it'd be nicer to
use the generic hex_dump, so use it instead.

<snorts> no print_hex_dump_dbg method exists either.

V2: Change the uncompilable print_hex_dump_dbg call to
    print_hex_dump_debug that actually could be compiled...

Or maybe just delete the driver altogether.

It'd probably be nice to one day create something
like drivers/net/ethernet/obsolete and eventually
kill off code for the stuff that hasn't been
supported or sold in the last 20 years.

Applied to net-next, thanks Joe.

I don't know what to do with "really old" drivers.  People still use
them, some via qemu or whatever.

But yeah this particular case is likely unused by anyone.
