+++ This bug was initially created as a clone of Bug #1250359 +++

Consider below scenario
1) rename FOP invoked on file 'x'
2) write is still in progress for file 'x'
3) rename takes a lock on old-parent
3) write-update txn blocked on old-parent
4) in rename_cbk, contri xattrs are removed and contribution is deleted and
lock is released
5) now write-update txn gets the lock and updates the wrong parent
