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

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Commit 5ed85684 ("reflog_expire(): new function in the reference
API", 12-12-2014) added a new function definition which included
the extern keyword.

While this is not an illegal use of the keyword, it is somewhat
unusual to include it in a function definition. (It would be
unique in the git codebase). Also, it triggers a warning from
sparse. In order to suppress the warning, simply remove the
extern keyword from reflog_expire() definition.

Hi Michael,

If you need to re-roll your 'mh/reflog-expire' series, could you
please squash this into the relevant patch.

Thanks!

ATB,
Ramsay Jones
