What originally cought my attention was that gen_essiv_salt has a
size_t return type and error paths that return -1 on failure.
Further investigation revealed that the error value is never checked
for. The encrypt_block function doesn't use the return value in any
way and simply continues onward.
Furthermore, the gen_essiv_salt function has an error case that emits
an error message but returns success state.
This patch modifes gen_essiv_salt to return an error status in all
error branches, changes the return type to ssize_t and adds a check
to encrypt_block if gen_essiv_salt fails.

We need to check for AES being in 128-cbc mode and not 256-cbc.
fscrypt supports only 128-cbc and 256-xts so far.

...if none is given. To be compatible with fscryptctl.

In XTS mode we don't need ESSIV, just use the block number
as tweak.
Also apply EVP_EncryptFinal().

This works currently by chance since the sizes match, but
that might change with different cipher setups.

No longer hard code AES-128-CBC, we support AES-256-XTS too.

The key length can be very long, for example in xts mode.
So we have to use the right sizes for block and iv lengths.

fscrypto is using the max key lenth (64), so we cannot use the
AES-128-ECB len.
