refs/files-backend: mark a file-local symbol static

Commit 6d41edc6 ("refs: add methods for reflog", 24-02-2016), moved the reflog handling into the ref-storage backend. In particular, the files_reflog_iterator_begin() API was removed from internal refs API header, resulting in sparse warnings.

Hi Michael,

If you need to re-roll your 'mh/ref-store' branch, could you please squash this into the relevant patch. (or something like it - if you think this function should be public, then re-introduce the declaration to the header).

Thanks!

ATB,
Ramsay Jones
