nilfs2: optimize rec_len functions This is a similar change to those in ext2/ext3 codebase (commit 40a063f6691ce937 and a4ae3094869f18e2, respectively). The addition of 64k block capability in the rec_len_from_disk and rec_len_to_disk functions added a bit of math overhead which slows down file create workloads needlessly when the architecture cannot even support 64k blocks. This will cut the corner. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
