f2fs: cleanup the disk level filename updating
As discuss with Jaegeuk and Chao,
"Once checkpoint is done, f2fs doesn't need to update there-in filename at all."
The disk-level filename is used only one case,
1. create a file A under a dir
2. sync A
3. godown
4. umount
5. mount (roll_forward)
Only the rename/cross_rename changes the filename, if it happens,
a. between step 1 and 2, the sync A will caused checkpoint, so that,
the roll_forward at step 5 never happens.
b. after step 2, the roll_forward happens, file A will roll forward
to the result as after step 1.
So that, any updating the disk filename is useless, just cleanup it.
