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.
