Subject: [PATCH] net: deprecate print_mac

We've had %pM for long enough now, time to deprecate
print_mac() and remove the __maybe_unused attribute
from DECLARE_MAC_BUF so that variables declared with
that can be found and removed. Otherwise people are
putting in new users of print_mac().

On my tree, with three other patches I have submitted
to gianfar, fcoe and wireless, there's now no user of
DECLARE_MAC_BUF() left. I'm open to just killing it
right away, but that seems like a pain to coordinate
and would likely get merge conflicts, so this is much
simpler and then killing it next cycle.
