QUIC: clear SSL_OP_ENABLE_MIDDLEBOX_COMPAT on SSL context switch.
The SSL_OP_ENABLE_MIDDLEBOX_COMPAT option is provided by QuicTLS and enabled
by default in the newly created SSL contexts. SSL_set_quic_method() is used
to clear it, which is required for SSL handshake to work on QUIC connections.
Switching context in the ngx_http_ssl_servername() SNI callback overrides SSL
options from the new SSL context. This results in the option set again.
Fix is to explicitly clear it when switching to another SSL context.
