[PATCH] tag.c: remove extern keyword from function definition

Hi Santiago,

If you need to re-roll your 'st/verify-tag' branch, could you
please squash this into the relevant patch (commit c5213b40,
"verify-tag: move tag verification code to tag.c", 19-04-2016).

Although not actually an error, it is very unusual for an extern
keyword to be used on a function definition (it seems to be getting
quite unusual on a function declaration these days!), which causes
sparse to issue a warning.

Thanks!

ATB,
Ramsay Jones
