Subject[PATCH] nvme-pci: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/nvme/host/pci.c: In function ‘nvme_timeout’:
drivers/nvme/host/pci.c:1298:12: warning: this statement may fall through [-Wimplicit-fallthrough=]
shutdown = true;
~~~~~~~~~^~~~~~
drivers/nvme/host/pci.c:1299:2: note: here
case NVME_CTRL_CONNECTING:
^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
