ext4: update the s_overhead_clusters in the backup sb's when resizing
When the EXT4_IOC_RESIZE_FS ioctl is complete, update the backup
superblocks. We don't do this for the old-style resize ioctls since
they are quite ancient, and only used by very old versions of
resize2fs --- and we don't want to update the backup superblocks every
time EXT4_IOC_GROUP_ADD is called, since it might get called a lot.
