Eric Biggers 1ebc569241 fscrypt: add IV_INO_LBLK_32 support for FS_ENCRYPTION_MODE_PRIVATE
With FS_ENCRYPTION_MODE_PRIVATE (AES-256-XTS inline encryption), add
support for the IV_INO_LBLK_32 IV generation method which adds the
SipHash of the inode number to the file logical block number mod 2^32.
The SipHash key is computed as SHA-256(master_key).
