Fix for HDFFV-10659: The library abort with "infinite loop closing library" after deleting attributes in densed storage. The fix: When deleting attribute nodes from the name index v2 B-tree, if an attribute is found in the intermediate B-tree nodes, which may be merged/redistributed in the process, we need to free the dynamically allocated spaces for the intermediate decoded attribute.
