f2fs: disable fsck check

fsck.f2fs does not fix any inconsistencies "yet".

Disable fsck routine as this is just wasting time consumed to mount f2fs volumes.

The kernel can determine if a f2fs volume is too damaged that it shouldn't get mounted.

We should wait for f2fs-tools version higher than v1.3.0.
(fsck.f2fs for fixing inconsistencies is a work-in-progress)
