[rds-devel] [PATCH 3/5] RDS: Fix panic on unload

[Andy Grover]

Remove explicit destruction of passive connection when destroying
active end of the connection. The passive end is also on the
device's connection list, and will thus be cleaned up properly.
Panic was caused by trying to clean it up twice.
