Fix issues in CC310 cc_internal discovered by OTT 

Return `MBEDTLS_ERR_ECP_INVALID_KEY` when Cryptocell returns
`CRYS_ECPKI_BUILD_KEY_INVALID_PRIV_KEY_SIZE_ERROR`
or `CRYS_ECPKI_BUILD_KEY_INVALID_PUBL_KEY_SIZE_ERROR`,
When the key size is invalid. Found by the "ECDSA zero private parameter"
tests.
