Switch error code to more appropriate value
Since we are internal rather than user-facing, PSA_ERROR_CORRUPTION_DETECTED makes more sense than PSA_ERROR_BUFFER_TOO_SMALL. Whilst it really is a buffer that is too small, this error code is intended to indicate that a user-supplied buffer is too small, not an internal one.
