Remove uses of MBEDTLS_ERR_SSL_INVALID_VERIFY_HASH

The error code MBEDTLS_ERR_SSL_INVALID_VERIFY_HASH is only
returned from the internal function

```
   mbedtls_ssl_set_calc_verify_md()
```

Moreover, at every call-site of this function, it is only
checked whether the return value is 0 or not, while the
exact return value is irrelevant.

The behavior the library is therefore unchanged if we return 1
instead of MBEDTLS_ERR_SSL_INVALID_VERIFY_HASH in
`mbedtls_ssl_set_calc_verify_md()`. This commit makes this change.
