-----------------------------------------------

This reverts commit acc5af3e ("ubifs: Fix out-of-bounds memory access caused by abnormal value of node_len")

No need to avoid memory oob in dumping for data node alone. Later, node
length will be passed into function 'ubifs_dump_node()' which replaces
all node dumping places.
