net/rds: An rds_sock is added too early to the hash table
[ Upstream commit c5c1a030a7dbf8dd4e1fa4405ae9a89dc1d2a8db ]
In rds_bind(), an rds_sock is added to the RDS bind hash table before
rs_transport is set. This means that the socket can be found by the
receive code path when rs_transport is NULL. And the receive code
path de-references rs_transport for congestion update check. This can
cause a panic. An rds_sock should not be added to the bind hash table
before all the needed fields are set.
