nilfs2: eliminate nilfs_btnode_get function
This removes the obsolete nilfs_btnode_get() function and makes nilfs_btree_get_block() directly call nilfs_btnode_submit_block(). This expansion will provide better opportunity for code optimization. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
