[PATCH 2/6] refs.c: remove lock_fd from struct ref_lock

The 'lock_fd' is the same as 'lk->fd'. No need to store it twice so remove it. You may argue this introduces more coupling as we need to know more about the internals of the lock file mechanism, but this will be solved in a later patch.

No functional changes intended.
