nvme: only allow entering LIVE from CONNECTING state

Browse Source 
[ Upstream commit d2fe192348 ]

The fabric transports and also the PCI transport are not entering the
LIVE state from NEW or RESETTING. This makes the state machine more
restrictive and allows to catch not supported state transitions, e.g.
directly switching from RESETTING to LIVE.
