    cluster/dht: Treat linkto file rename failure as non-critial error
    
    It is a critical failure iff we fail to rename the cached file
    if the rename of the linkto failed, it is not a critical failure,
    and we do not want to lose the created hard link for the new
    name as that could have been read by other clients.
    
    NOTE: If another client is attempting the same oldname -> newname
    rename, and finds both file names as existing, and are hard links
    to each other, then FUSE would send in an unlink for oldname. In
    this time duration if we treat the linkto as a critical error and
    unlink the newname we created, we would have effectively lost the
    file to rename operations.
    
    Repercussions of treating this as a non-critical error is that
    we could leave behind a stale linkto file and/or not create the new
    linkto file, the second case would be rectified by a subsequent
    lookup, the first case by a rebalance, like for all stale linkto
    files

    cluster/dht: Rename should not fail post hardlink creation
    
    In the rename path, we wind the creation of newname hardlink and
    linkto file in dst hashed a the same time. If the linkto creation
    fails, but the link creation succeeds, we enter the failure code
    and cleanup the created newname hardlink.
    
    In the interim if another client looks up newname and finds it as
    a hardlink from FUSE, it could send an unlink for oldname instead
    of a rename. This combined with the above cleanup code could end
    up losing all the files copies, and thereby losing data.
    
    This fix separates these steps into 2 parts, creating the linkto
    first and then the link file, so that post link file creation no
    failures would cleanup the newname file. If linkto fails then link
    is not attempted, thereby not polluting the name space with
    newname.

    cluster/dht: remove specifying cached-subvol as part of name in
    unlink.
    
    commit 667b2496c3f29e24ed359a05b0f44df0d1894969 introduced a
    functionality where we can specify the subvol where file is stored. As
    part of same commit, dht_unlink was also changed to accept
    cached-subvol as part of name. While it makes sense to specify subvol
    while creating file, there is no necessity for specifying the subvol
    during unlink, since the default unlink logic works fine with this
    functionality too. Also, this code in unlink doesn't work well when
    files get migrated by rebalance process. Hence removing it.
