nilfs2: convert nilfs_bmap_lookup to an inline function
The nilfs_bmap_lookup() is now a wrapper function of nilfs_bmap_lookup_at_level(). This moves the nilfs_bmap_lookup() to a header file converting it to an inline function and gives an opportunity for optimization. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
