grub_util_get_dm_abstraction() does a string comparison of insufficient
length. When using a UUID such as "CRYPT-PLAIN-sda6_crypt", the function
returns GRUB_DEV_ABSTRACTION_LUKS.
This results in the error:
./grub-probe: error: disk `cryptouuid/sda6_crypt' not found.
This appears to be a copy/paste error introduced in:

The bug was (apparently) latent until revealed by:
