quota/marker: set lk_owner when taking lock on parent in rename
This is a backport of http://review.gluster.org/#/c/11561/
Before doing a rename operation marker takes inode lock on the file

here lk_owner is NULL and this can cause accounting problem with
multiple rename on the same directory
This patch fix the problem by setting lk_owner
