For future reference, kernel module mismatches can't cause this type of
error.  The relevant bit of GRUB's filesystem handling runs in
userspace, and only needs access to the block device.

The syslog shows that 2.02+dfsg1-13 was installed.  I already fixed this
in 2.02+dfsg1-14 - it's just not in testing yet:

grub2 (2.02+dfsg1-14) unstable; urgency=medium

  * Make signed packages depend on a matching version of grub-common, in an
    attempt to prevent incorrect testing migrations (closes: #924814).
  * Cherry-pick from upstream:
    - xfs: Accept filesystem with sparse inodes (closes: #924760).
  * Minimise writes to EFI variable storage (closes: #891434).
