In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
In file included from drivers/scsi/dmx3191d.c:48:
drivers/scsi/NCR5380.c: In function ‘NCR5380_information_transfer’:
drivers/scsi/NCR5380.c:1933:9: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (!hostdata->connected)
^
drivers/scsi/NCR5380.c:1937:5: note: here
default:
^~~~~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

Changes in v2:
- Update commit log.
- Move code comment after the default label and
retain reason for fall-through in comment as
requested by Michael Schmitz.
