Fix refs.c;:repack_without_ref() clean-up path

The function repack_without_ref() passes a lock-file structure
on the stack to hold_lock_file_for_update(), which in turn
registers it to be cleaned up via atexit().  This is a big
no-no.

This is the same bug James Bottomley fixed with commit
31f584c242e7af28018ff920b6c8d1952beadbd4.
