      Description

      Currently INode#cleanSubtree is used to delete files/directories and collect corresponding blocks for future deletion. Its return value can be 0 even if file/dir has been deleted because we save snapshot copies. This breaks the original logic in FSDirectory#delete since FSDirectory#delete expects a positive value from a successful deletion.
