Wenwen Wang ce4d8b16e6 ubifs: Fix memory leak in read_znode() error path ...

In read_znode(), the indexing node 'idx' is allocated by kmalloc().
However, it is not deallocated in the following execution if
ubifs_node_check_hash() fails, leading to a memory leak bug. To fix this
issue, free 'idx' before returning the error.
