nilfs2: add sanity check in nilfs_btree_add_dirty_buffer According to the report titled "problem with nilfs_cleanerd" from Łukasz Wójcicki, nilfs_btree_lookup_dirty_buffers or nilfs_btree_add_dirty_buffer got memory violation during garbage collection. This could happen if a level field of given btree node buffer is incorrect, which is a crucial internal bug. This inserts a sanity check to figure out the problem.
