Ryusuke Konishi ae191838b0 nilfs2: optimize rec_len functions
This is a similar change to those in ext2/ext3 codebase (commit
40a063f669 and a4ae309486, 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.
