[roll] Roll fuchsia [f2fs] Add range checkers for checkpoint packs

This CL adds checking the validity for some fields that
a checkpoint pack have such as the sizes of nat/sit version bitmaps
and the next free node id. If they are invalid, it stops mounting
since it means that there is corruption on the read-only superblock
or the checkpoint pack.
