QUIC: fixed encryption level in ngx_quic_frame_sendto(). Previously, ssl_encryption_application was hardcoded. Before 9553eea74f2a, ngx_quic_frame_sendto() was used only for PATH_CHALLENGE/PATH_RESPONSE sent at the application level only. Since 9553eea74f2a, ngx_quic_frame_sendto() is also used for CONNECTION_CLOSE, which can be sent at initial level after SSL handshake error or rejection. This resulted in packet encryption error. Now level is copied from frame, which fixes the error.
