In port_bind_channel(), when ossl_quic_provide_initial_secret() fails, the function returns without freeing the QUIC_CHANNEL that was just created by port_make_channel(). The caller sees new_ch == NULL and cannot free it, leaking the channel and all its sub-allocations (QRX, QTX, TXP, ACKM). Add ossl_quic_channel_free(ch) before the early return, matching the cleanup pattern already used by the other error paths in the same function (lines 864, 873).
