generic/067 mounts $SCRATCH_DEV directly in the test, assuming it's a block device. generic/299 and generic/300 query the size of $SCRATCH_DEV by running 'blockdev --getsz $SCRATCH_DEV'. So add the check to make sure $SCRATCH_DEV is a real block device in these tests. Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>

# Test will operate on huge sparsed file so ENOSPC is expected.
