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.
