[PATCH/RFC] deprecate print_mac

[Johannes Berg <johannes@sipsolutions.net>]

Or more precisely, deprecate the variables that DECLARE_MAC_BUF
creates, DECLARE_MAC_BUF is required for print_mac and the latter
uses the created variables.

I don't think we want this without the bulk of the users removed. And
after that, it should be removed before long anyway.
