As read_mmp_block return 1 when failed. read_mmp_block return -EIO when buffer
isn't uptodate.

Thank you for this second patch. Unfortunately, the commit message
is still confusing/incorrect because it references read_mmp_block()
in the first usage but is actually changing write_mmp_block().
With that change you could add a Reviewed-by label from me.
