[U-Boot] ext4: Issue with ext4write

Hi all,

I am sometimes seeing issues when using ext4write where fsck later complains that the group descriptor has an invalid number of unused inodes. Is this a known problem?

Also, I think the assert(offset == sizeof(*desc)); in ext4fs_checksum_update() is invalid since with ext4 the descriptor is larger than the offset. When debugging was enabled I'd always hit this assert.

Also, in ext4fs_write, the debug statement should say blocks and not bytes.
