Don't complain with "no cipher match" for QUIC objects 

Calling the functions SSL_CTX_set_cipher_list() or SSL_set_cipher_list() will
return the error "no cipher match" if no TLSv1.2 (or below) ciphers are enabled
after calling them. However this is normal behaviour for QUIC objects which do
not support TLSv1.2 ciphers. Therefore we should suppress that error in this
case.

Fixes #25878
