I'm seeing the same error. I found the message mysterious, so I took a look at the code and discovered the following:
- "diskfilter" is GRUB's implementation detail for working with LVM and MD RAID
  devices.
- Writing to these kinds of devices is not implemented in GRUB.
- The error may have always been there, but
  0085-grub-core-disk-diskfilter.c-grub_diskfilter_write-Ca.patch made it more
  visible.
- The reason GRUB is trying to write to the device could be it's following
  the "save_env" commands in the config file.
