Minus does not mean equals.
Besides fixing an obvious bug, this avoids the following compiler
warning with clang -Wall:
tune2fs.c:3625:20: warning: expression result unused [-Wunused-value]
fsuuid->fsu_len - UUID_SIZE;
~~~~~~~~~~~~~~~ ^ ~~~~~~~~~
Fixes: a83e199da0ca ("tune2fs: Add support for get/set UUID ioctls.")
