MINOR: check: reject invalid check config on a QUIC server

Browse Source 
QUIC is now supported on the backend side. The previous commit ensures
that simple checks can be activated on QUIC servers without any issue.

The current patch ensures that check server settings remain compatible
with a QUIC server. Thus, configuration is now invalid if check
specifies an explicit MUX proto other than QUIC, disables SSL or try to
use PROXY protocol.
