Previously the GRPC stream context was used to update the ring state back to PENDING after a failed chunk transfer.
However if the transfer failed because of a GRPC error this context would get canceled and this would prevent Loki from updating the ring state and it would force an os.Exit
This change uses a new context to update the ring state after a failed transfer to avoid this issue and also makes the error message more clear to explain why the loki process exits.
