Subject: [PATCH 4/5] ext4: fix super block checksum error

From: Ye Bin <yebin10@...wei.com>

As commit("ext4: fix error flag covered by journal recovery") update
error record when do journal recovery.There is need to recalculate
super block checksum after update error record or will lead to super
block checksum mismatch to data.
