history: initialize rev_info in cmd_history_reword()
git history reword expects a single valid revision argument and errors out if it doesn't get it. In that case the struct rev_info passed to release_revisions() for cleanup is still uninitialized, which can result in attempts to free(3) random pointers. Avoid that by initializing the structure.
