Ocean Chen dd1fc2ce32 f2fs: avoid out-of-range memory access
[ Upstream commit 56f3ce675103e3fb9e631cfb4131fc768bc23e9a ]

blkoff_off might over 512 due to fs corrupt or security
vulnerability. That should be checked before being using.

Use ENTRIES_IN_SUM to protect invalid value in cur_data_blkoff.
