[PATCH v4 1/5] nvme core: allow controller RESETTING to RECONNECTING transition

[jsmart2021@gmail.com (James Smart)]

Allow controller state transition : RESETTING to RECONNECTING

Transport will typically transition from LIVE->RESETTING when
initially performing a reset or recovering from an error. Adding
this transition allows a transport to transition to RECONNECTING
when it checks/waits for connectivity then creates new transport
connections and reinits the controller.
