    geo-rep: hard-link rename issues on changelog replay

    Problem:
    LINK + RENAME changelog when replayed after worker restart causes stale
    hard-links to persist since VFS returns success for RENAME if hard-links
    point to same inode.

    Solution:
    Worker detects RENAME being issued on hard-links to the same inode and
    unlinks the source file-name. Conditionally rename by verifying that the
    source gfid matches with the on-disk gfid on the slave.
