nilfs2: remove redundant pointer checks in bmap lookup functions
nilfs_bmap_lookup and its variants are supposed to take a valid pointer argument to return a block address, thus pointer checks in nilfs_btree_lookup and nilfs_direct_lookup are needless. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
