Hmm.. f2fs_sanity_check_ckpt() is not used in super.c and there-in code logic is
not related to super.c too, instead, it is all related to checkpoint.c.

So I just want to unify maintaining checkpoint related functions, it may make
code more clean.

Anyway, it's trivial cleanup, please ignore this patch if you don't want to do
such relocation.

Thanks,
