since 64-bit inodes can be accessed while using inode32, and these can also be
used on 32-bit kernels, there is no reason to still keep inode32 as the default
mount option.
If the filesystem cannot handle 64bit inode numbers (i.e CONFIG_LBDAF is not
enabled and BITS_PER_LONG == 32), XFS_MOUNT_SMALL_INUMS will still be set by
default, so inode64 is not an unconditional default value.
