We had this check in the non-PSA case, but it was missing in the PSA
case.

+Bugfix
+ * Fix a bug in (D)TLS curve negotiation: when MBEDTLS_USE_PSA_CRYPTO was
+ enabled and an ECDHE-ECDSA or ECDHE-RSA key exchange was used, the
+ client would fail to check that the curve selected by the server for
+ ECDHE was indeed one that was offered. As a result, the client would
+ accept any curve that it supported, even if that curve was not allowed
+ according to its configuration.
