Fix ASAN error for `psa_cipher_update`

The ASAN gives an error for `psa_cipher_update` when the `input_length`
is 0 and the `input` buffer is `NULL`. The root cause of this issue is
`mbedtls_cipher_update` always need a valid pointer for the
input buffer even if the length is 0.
This fix avoids the `mbedtls_cipher_update` to be called if the
input buffer length is 0.
