scripts/checkpatch.pl reports about some style problems,
this commit fixes some of them:

Thanks, applied to trivial-patches queue.

I'm a bit afraid of this sort of patches - there are LOTS of
coding style issues in current qemu code base, and applying
a patch like this may open a really large can of worms...

Generally it has been agreed to fix coding style only when
doing some other code changes nearby, as far as I remember.

Some times ago there was a patch on adding DEC Tulip NIC support
(see http://lists.gnu.org/archive/html/qemu-devel/2013-11/msg02878.html).

In this patch the 93LC46B Serial EEPROM emulation was added.
But it's like reinventing the wheel because Stefan Weil already
have done this work in 2006! So I used eeprom93xx for the next
tulip patch version and occasionally I fixed some coding style issues.
