psa_raw_key_agreement() returned PSA_ERROR_INVALID_ARGUMENT instead of PSA_ERROR_BUFFER_TOO_SMALL when the output buffer was too small for ECDH, the only algorithm that is currently implemented. Make it return the correct error code. The reason for the wrong error code is that ecdh.c returns MBEDTLS_ERR_ECP_BAD_INPUT_DATA, presumably for similarith with dhm.c. It might make sense to change ecdh.c to use MBEDTLS_ERR_ECP_BUFFER_TOO_SMALL, but dhm.c doesn't have an existing BUFFER_TOO_SMALL error. To minimize the impact of the fix, handle this in the PSA layer. Fixes #5735. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
