libblkid: jfs - avoid undefined shift

Fix previous commit 04a0717b0b0faa1a8078dc6fad05183b8bada395
to avoid undefined shift if value is exactly 32.

  libblkid/src/superblocks/jfs.c:46:39: runtime error:
  shift exponent 32 is too large for 32-bit type 'unsigned int'

Reproducer found with OSS-Fuzz (issue 59284) running over
cryptsetup project (blkid is used in header init).
