[PATCH v2 06/24] expire_reflog(): return early if the reference has no reflog

There is very little cleanup needed if the reference has no reflog. If we move the initialization of log_file down a bit, there's even less. So instead of jumping to the cleanup code at the end of the function, just do the cleanup and return inline.
