The set_blocksize (which is in sb_set_blocksize) will fail
if a blocksize is too small:

	/* Size cannot be smaller than the size supported by the device */
	if (size < bdev_logical_block_size(bdev))
		return -EINVAL;

Therefore remove the checking for small blocksize before "sb_set_blocksize"
to make it consistent to ext2.
