[ Upstream commit d3d380eded7ee5fc2fc53b3b0e72365ded025c4a ]
The initial controller initialization mimiks the reconnect loop behavior by switching from NEW to RESETTING and then to CONNECTING.
The transition from NEW to CONNECTING is a valid transition, so there is no point entering the RESETTING state. TCP and RDMA also transition directly to CONNECTING state.
