rds_tcp_connection allocation/free management has the potential to be called from __rds_conn_create after IRQs have been disabled, so spin_[un]lock_bh cannot be used with rds_tcp_conn_lock. Bottom-halves that need to synchronize for critical sections protected by rds_tcp_conn_lock should instead use rds_destroy_pending() correctly.
