ext4: fix bad checksum after online resize
commit a408f33e895e455f16cf964cb5cd4979b658db7b upstream.
When online resizing is performed twice consecutively, the error message
"Superblock checksum does not match superblock" is displayed for the
second time. Here's the reproducer:
mkfs.ext4 -F /dev/sdb 100M
mount /dev/sdb /tmp/test
resize2fs /dev/sdb 5G
resize2fs /dev/sdb 6G
To solve this issue, we moved the update of the checksum after the
es->s_overhead_clusters is updated.
