[PATCH 1/3] nvme-pci: Fix timeouts in connecting state

[keith.busch@intel.com (Keith Busch)]

We need to halt the controller immediately if we haven't completed
initialization as indicated by the new "connecting" state.

Fixes: ad70062cdb ("nvme-pci: introduce RECONNECTING state to mark initializing procedure")
