Subject: nvme: modify the debug level for setting shutdown timeout
Patch-mainline: v4.16-rc1
Git-commit: 1a3838d732eaae47385490de88d978d4132d3d84
References: FATE#323952, FATE#322506

When an NVMe controller reports RTD3 Entry Latency larger than the value
of shutdown_timeout module parameter, we update the shutdown_timeout
accordingly to honor RTD3 Entry Latency. Use an informational debug level
instead of a warning level for it.
