[PATCH v4 1/3] nvme-fc: go straight to connecting state when initializing

[Daniel Wagner]

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.
