    cluster/afr: Make entry-self-heal in afr-v2 compatible with afr-v1

    Problem:
    entry self-heal in 3.6 and above, takes full lock on the directory only for
the
    duration of figuring out the xattrs of the directories where as 3.5 takes
locks
    through out the entry-self-heal. If the cluster is heterogeneous then there
is
    a chance that 3.6 self-heal is triggered and then 3.5 self-heal will also
    triggered and both the self-heal daemons of 3.5 and 3.6 do self-heal.

    Fix:
    In 3.6.x and above get an entry lock on a very long name before entry
self-heal
    begins so that 3.5 entry self-heal will not get locks until 3.6.x entry
    self-heal completes.
