Subject: disconnect: set conn->data for protocol disconnect

Follow-up to fb445a1e18d: Set conn->data explicitly to point out the
current transfer when invoking the protocol-specific disconnect function
so that it can work correctly.

Bug: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=12173
