MINOR: quic+openssl_compat: Do not start without "limited-quic"

Add a check for limited-quic in check_config_validity() when compiled
with USE_QUIC_OPENSSL_COMPAT so that we prevent a config from starting
accidentally with limited QUIC support. If a QUIC listener is found
when using the compatibility mode and limited-quic is not set, an error
message is reported explaining that the SSL library is not compatible
and proposing the user to enable limited-quic if that's what they want,
and the startup fails.

This partially reverts commit 7c730803d ("MINOR: quic: Warning for
OpenSSL wrapper QUIC bindings without "limited-quic"") since a warning
was not sufficient.
