This relies on the caller to detect and report an error if the user has configured QEMU with x509 credentials on a UNIX socket. The migration code has such a check, but it is too broad, reporting an error when the user has configured QEMU with PSK credentials on a UNIX socket, where hostnames are irrelevant. Putting the check into the TLS session object credentials validation code ensures we report errors in only the scenario that matters. Signed-off-by: Daniel P.
