James Smart 834d3710a0 nvme-fc: reject reconnect if io queue count is reduced to zero ... If: - A successful connect has occurred with an io queue count greater than zero and namespaces detected and running. - An error or something occurs which causes a termination of the prior association and then starts a reconnect, - The reconnect then creates a new controller, but for whatever reason, nvme_set_queue_count() results in io queue count set to zero. This will skip io queue and tag set changes. - But... the controller will transition to live, calling nvme_start_ctrl, which calls nvme_start_queues(), which then releases I/Os into the transport which then sends them to the driver. As there are no queues, things eventually hit the driver looking for a handle, which was cleared when the original controller was reset, and it can't proceed. Worst case, things progress, but everything fails. In the failing scenario, the nvme_set_features(NVME_FEAT_NUM_QUEUES) command actually failed with a NVME_SC_INTERNAL error. For some reason, although nvme_set_queue_count() saw the error and set io queue count to zero, it doesn't return a failure status to the transport, which allows the transport to continue using the controller. Fix the problem by simply rejecting the new association if at least 1 I/O queue can't be created. The association reject will fail the reconnect attempt and fall into the reconnect retry policy.
