QUIC: removed excessive check. The c->udp->dgram may be NULL only if the quic connection was just created: the ngx_event_udp_recvmsg() passes information about datagrams to existing connections by providing information in c->udp. If case of a new connection, c->udp is allocated by the QUIC code during creation of quic connection (it uses c->sockaddr to initialize qsock->path). Thus the check for qsock->path is excessive and can be read wrong, assuming that other options possible, leading to warnings from clang static analyzer.
