Print error if blkid falid and add --disable-blkid option for luksFormat.
If old util-linux is used, blkid scan can fail because disk is already locked for OPAL.
Also add some debug messages to be clear what's going on.
See comments in !531 (comment 1532181741)
Also add --disable-blkid option (applies only to CLI tools).
