QUIC: got rid of excessive "qsock" argument in ngx_quic_output.c.
The output is always sent to the active path, which is stored in the
quic connection. There is no need to pass it in arguments.
When output has to be send to to a specific path (in rare cases, such as
path probing), a separate method exists (ngx_quic_frame_sendto()).
