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.
