Baokun Li c2bd60ef20 ext4: fix bad checksum after online resize 
commit a408f33e89 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.

Fixes: 026d0d27c4 ("ext4: reduce computation of overhead during resize")
Fixes: de394a8665 ("ext4: update s_overhead_clusters in the superblock during an on-line resize")
